Hi Herbert,

Thanks for testing! The patch needs one more change though as
moving the atomic_inc outside of the lock was a bad idea on my
part.  This could cause atomic_inc/atomic_dec to be reordered
thus resulting in an underflow.

I want to confirm that this patch fixes massive strangenesses and
few crashes observed on s390 systems, in addition to OOMs reported
by Mikhail Zaslonko earlier.

Thanks,

Thanks!
