There is at least one place where sigacts locking trips this assertion.
I will try to work on cleaning up that and other problems that surface
today from this check.

I also need to add a KASSERT() to msleep/cv_wait* that we don't try
to sleep if we are already on a sleep queue.  It seems that using
ptrace can trip that as well. :(
