In previous instances of these hangs, a reboot has always fixed them. I had the
idea that the hangs might be related to permissions of cache files in
/var/folders, but a recent ticket seems to have disproved that. If you feel like
debugging these hangs with dtruss(1), that would be very welcome. Try also
blowing away your /var/folders/* (although at this point I have little hope that
it will help).

Otherwise, just reboot and enjoy your Windows-like system.
