By the way, it doesn't freeze with debug.mpsafenet=0.  However, the 
interrupt time is still really high.  With witness disabled (sysctl 
debug.witness.watch=0) but invariants enabled I got the following 
snapshot from systat -vm while copying over the thunderbird source from 
another machine via scp:

68% for 551 interrupts?
