Why do I say "non-interrupt blocking?". Currently we have roughly a
half dozen locking primitives. The two that I am familiar with are
blocking and spinning mutexes. The general policy is to use blocking
locks except where a lock is used in interrupts or
I apologize if this e-mail seems a bit disjoint, I'm quite tired from

I'm not entirely familiar with the system as a whole - but to give a

Not by using top(1). vmstat seems to do
I have a number of issues with our current locking regime and our
propensity for disabling interrupts. I have in mind some ideas for
reducing interrupt disabling and eliminating scheduling contention
except in the case of one cpu stealing a thread from another cpu's
runqueue. I'll try to dash that

output does cpustat provide on DragonflyBSD?
Its a simple output such as:
CPU-0 state: 14.00% user, 0.00% nice, 2.00%
sys, 6.00% intr, 78.00% idle
CPU-1 state: 4.00% us

I need to gauge the efficiency of SMP for a particular application, and
