"When I find the controls, I'll go where I like, I'll know where I want
to be, but maybe for now I'll stay right here on a silent sea."
KT Tunstall, Silent Sea, Eye to the Telescope, 2004.
>Environment:
	Probably irrelevant, but got for a netbsd32 process on an amd64 system.
>How-To-Repeat:
	Run regress/lib/libpthread/sigalarm with a LOCKDEBUG kernel.

	What happens is that kpsignal2 does a lot of things under SCHED_LOCK,
	notably calling ksiginfo_put() in some situations.  That function calls
	pool_get() which triggers the assertion.
>Fix:
	Move the assertion in the WAITOK case in pool_get?
