Terry Wilson 9be8ebb96c Make signal handling order predictable 
Due to the unordered nature of sets, it is possible for signal
handlers like _gracefull_shutdown() to run first and clear the
_signal_handlers before other registered handlers have run.

This patch converts _signal_handlers from a set to a list and
then runs the handlers LIFO similar to how atexit functions are
run. Given that the handlers added in service.py are added after
clearing the signal_handlers, they are guaranteed to be the first
in the list and the last run.
