I thought I did a clean compile (ant clean && ant for core and gui)
time to man cvs

Anyway, I checked the new sharing options, but couldn't find a way to stop the media folders from being automatically shared.

The stop sharing item in the contextual menu is greyed out currently, but I'll keep checking. I like to check out a file before sharing it back, so I hope that will be an available option.

re the SocketException: Invalid argument errors, they're back again to their usual frequency. Perhaps restarting the iBook earlier today made an initial difference.

Thanks for the tips.
