[ slow deleting of 25GB, horrible latency ]

Hmmm, I'd be curious to see how 2.4.9-ac16 (or 2.4.10) performs there. The
reiserfs delete code should be scheduling enough due to transaction
stop/starts that interactive performance isn't that bad.

You should be able to repeat your results by doing the same tests on sparse
files:

dd if=/dev/zero of=foo bs=1M count=1 seek=250000
