Go ahead and send-pr it; the problem has been known for a while and I
haven't yet fixed it, but it's good to have a record. The problem is
that somehow LWPs are sticking around on the alllwp list after the
process has exited. Eventually uvm_swapout_threads() iterates over
alllwp and examines l->l_proc->p_flag of every lwp, and at some point
l->l_proc of the dead lwp ceases to point to valid memory (pool
reclamation?) and it goes boom.
