Мелочь, но эту строчку нужно вынести за try.
Потому что есть signa.signal вывалится с ошибкой то в finally возвращать старый обработчик не нужно (он и так стоит), да и не из чего (handler еще не присвоет и просто не существует).
Аналогично, например, нужно делать с блокировками без with:
l = RLock()
# ....
l.acquire()
try:
do_something()
finally:
l.release()
