I started working on this patch which causes pipes to always
be closed during timer thread shutdown.

However, I may also eliminate timer thread entirely (on POSIX) by
using timer_create+timer_settime to deliver SIGVTALRM.

I also eliminated malloc from signal thread list (but not FGLOCK, yet),
but eliminating malloc may not be necessary.
