Interesting... I wonder what the lock contention path is between the VM
and network stack. Has anyone else noticed this in their testing? Did
you try a post-5.3 release or not? rwatson@ just MFC'ed a bunch of
network locking fixes to RELENG_5, but none-stand out in my mind as
being something that'd potentially fix your issue. Actually, he
probably knows better than anyone what this could be. Some of the post
RELENG_5_3 commits by alc@ could explain this, however, and is why I
ask what the specific version/build time is for your release. -sc
