This reenables the stack backtrace support of monitr when receiving a SIGHUP.

In addition, code is now more thread-friendly. Note that signals can be delivered to any thread inside a process which has not blocked the signal.

SIGHUP catcher uses only async-safe functions

sets a sig_atomic_t variable
calls write() to write a single character to the end of the pipe which the monitor thread is about to read
