I've encountered the ops drop to zero problem also while running spec.
It was introduced by a fix to another bug. I am going to undo that fix
for now. The io stop problem is much more probable than the spinlock
deadlock that we were trying to fix. We should make a patch to submittal
once I check this in.

Due to 21174 (PS drops ZERO after 5-6 minutes of traffic) and  21739
(drop in nfs throughput after mapping the same volumes cifs share), its
becoming next to impossible populating the file systems.=20
