I've got some mysterious, possibly similar, experiences today.

Setup is an MB with Lion & Crucial SSD.
Upon ODS'ing the SSD i started removing some directories through ODS. Now free space as listed by the finder and as listed by the activity monitor diverged, giving me a difference of about 30GB (quite a bunch).

I rebooted and started the harddisktool. checking the system suddenly both figures (empty space shown in finder and empty space shown in the activity monitor) jumped up a further 30GB (which seems to be more realistic after i removed quite a lot of stuff).

My perception was that ODS removed the files from the SSD filesystem but some components of Mac OS did not realize that. All the time the free space in the Activity Monitor stayed about put.

Will do another reboot now, this feels definitely a bit awkward.
