LR 2.0 Synchronization hangs

Question

Is anybody else seeing this, hopefully with a solution or workaround?
When I try to synchronize some folders with more than around 120 files, LR shows the progress up to 25% or so in its titlebar, and then - nothing. The percent complete vanishes from the titlebar, and LR never finishes the sync. I left it running Synchronize Folder on a folder with just over 800 images (by its count in the folder panel) for over 8 hours today while I was out of the office, and it never finished even the "Import new photos(counting)" portion. Synchronizing individual sub-folders of that folder with 90-120 files works fine, completing each one in under a minute, but one with 128 files hangs.
Any tips, fixes, or workarounds greatly appreciated!

I discovered similar non-linear performance problems when generating
previews. The time to generate each preview increased as the number of
previews increased. With a small number of previews, LR 2 could generate
one preview per second. As the number of previews increased, the time to
generate a single preview increased to ten seconds per preview, and at
40,000 images, LR 2 could not generate even one preview in several hours.
After a week of trying to get it to work, I finally had to remove LR 2. I'm
waiting for the release that fixes these performance problems.
Best,
