exclusive sleep mutex sigacts

[Steve Kargl]

John,

I believe you've already seen the assertion fire, so this
may be redundant info:


kernel: checking stopevent 2 with the following non-sleepable \
locks held:
kernel: exclusive sleep mutex sigacts r = 0 (0xc4a25aa8) locked \
locked @ /usr/src/sys/kern/subr_trap.c:260

Note the assertation also flags

sys/kern/kern_synch.c:293
sys/kern/keren_condvar.c:289
