Not sure. Can you reproduce this problem without compressed cache
patch?

Still hard to say. If you can't reproduce with vanilla, please test
again with 0.21pre7 (there's a small fix for vswap). In the case the
problem is still there, tell me exactly what's your configuration like
and what you are trying to do (only allocation, for example, or
running a normal desktop with browser, etc) so I may be able to
reproduce it here.
