How can I keep AppleScript repeat resetting Safari in the background?

Question

I want to have an AppleScript which resets Safari every 10 seconds. Now I got a problem with repeating the script. After the script resets Safari it closes the app. I want to keep Safari open while the script is operating in the background.
That was my try:
=================
tell application "Safari" to launch
          tell application "Safari" to activate
          tell application "Safari" to open location "http://www.apple.com"
repeat
          tell application "Safari" to close every window
          try
                    tell application "Safari" to quit
          on error errmsg
                    display dialog "Safari App beenden gescheitert" with icon caution
          end try
          try
                    do shell script "rm -f ~/Library/Safari/history.plist"
          on error errmsg
                    display dialog "history.plist löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -f ~/Library/Safari/HistoryIndex.sk"
          on error errmsg
                    display dialog "HistoryIndex.sk löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -f ~/Library/Caches/com.apple.Safari/Cache.db"
          on error errmsg
                    display dialog "Cache.db löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -rf ~/Library/Caches/Metadata/Safari/History"
          on error errmsg
                    display dialog "History löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -f ~/Library/Cookies/Cookies.plist"
          on error errmsg
                    display dialog "Cookies.plist löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -f ~/Library/Safari/LastSession.plist"
          on error errmsg
                    display dialog "LastSession.plist löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -f ~/Library/Safari/TopSites.plist"
          on error errmsg
                    display dialog "TopSites.plist löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -rf ~/Library/Caches/com.Apple.Safari/*"
          on error errmsg
                    display dialog "Safari Cache löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -f ~/Library/Caches/Adobe/Flash Player/AssetCache"
          on error errmsg
                    display dialog "Flash Player AssetCache löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -rf ~/Library/Preferences/Macromedia/Flash*/macromedia.com/support/flashplayer/sys/ #*"
          on error errmsg
                    display dialog "Flash Player macromedia.com löschen gescheitert" with icon caution
          end try
          try
                    do shell script "rm -rf ~/Library/Preferences/Macromedia/Flash*/#SharedObjects/*"
          on error errmsg
                    display dialog "Flash Player #SharedObjects löschen gescheitert" with icon caution
          end try
  delay 10
end repeat

You can use the applescript Script Menu to run scripts in Photoshop (or any application).
If you don't have it installed, run the AppleScript Utility.app (find it in the Applescript folder in your applications folder) and make sure the 'Show Script Menu in menu bar' is checked.
Edit: I thought you'd be able to use this with an action by inserting a menu item, but apparently it doesn't recognize the appescript menu.
