That would be great.  I'm currently running 2.4.18.  I'm always up for
things that would help improve performance, even if they are "experimental".

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.

Regards,
	Dieter
