While testing some new pipe code, I'm occasionally seeing a timerfd deadlock:
The main thread is stuck in timerfd_tracker::dtor at timerfd.cc:354, waiting for
the timerfd thread to close; and the timerfd thread is stuck at timerfd.cc:140,
waiting to acquire a mutex that's held by timerfd_tracker::dtor.
I see this maybe 1 out of 4 times that I run 'make -j13' on a clean emacs source
tree, and I see it only when my new pipe code is installed. So I don't know if
this is a bug in my code or if it's just coincidence that my code happens to
trigger a timerfd bug.
