FreeBSD doesn't have the VM leak anymore (nor does BSDI.) It isn't all that
hard to fix and is mostly an exercise in data structures. No big rewrite

Try FreeBSD, if you are running on X86 machines. It's VM perf is better
than Linux in most respects, and in -current blows it away. Also, FreeBSD
really works under load.
