What specifically does the "I/O Safety Buffer" do?

Question

In Logic 8, in the preferences under audio there is a new box you can check that says I/O Safety buffer. It seems to enable use of logic at lower buffer rates. Whats it doing and how? the manual says nothing about this feature. It must have been added after the manual. I can get the buffer down to 32 when its checked. but if I strum my guitar over and over, after about 30 seconds there is a dropout, not a pop or click, but all sound stopping for a second then everything is fine again. Is this the down side of using this new feature?
Thanks

Hi,
This is what it does:
When you set the buffer to, for example, 11 milliseconds maximum latency, then any track that has plugins inserted in it, who have a total latency of LESS than 11 mS, operate NORMALLY.
Any track that has plugins that add up to MORE than 11 mS, then Logic automatically turns OFF some of the plugins, until it reaches the 11 mS or less maximum latency.
This is so that when you are playing live recording into Logic, you do not get a large latency that can throw off your playing.
I think what you're describing is the "low-latency" option.
