Under what circumstances would I see something like this happen (ext3)?
[rohan@box1 ~]$ df
Filesystem Total Used Free
/dev/partition 10000 9990 0
[rohan@box1 ~]$ rm <some files on that partition>
[rohan@box1 ~]$ df
Filesystem Total Used Free
/dev/partition 10000 9700 0
So the number of blocks in use went down, but the number free did not
increase. Why?

The space you've freed up is probably reserved for root and the
various process run as root. In order to prevent the system from
crashing it will report no free space to normal users when there is
clearly some there once a certain threshold is reached.
