If you are somewhat open for "new" (experimental) stuff I can prepare a patch 
on top of 2.4.18 or 2.4.19-pre2 for you.

But Andrea Arcangeli informed me that vm-29 had a deadlock bug in the recent 
fixes for the bh headers. vm-28 is fine or soon to be available vm-30.

It didn't hit me for the last two days.
