Hi, there.
I was trying to use uWSGI signals to communicate between a programmed mule
and the app's workers.
I assumed that if the mule sent uwsgi.signal(MY_NUMBER, 'workers') then my
handler would be executed once per worker. However, most of the time it's
only executed once (I have two workers). Only *sometimes* both workers
actually run the handler (the mule sleeps for a few seconds and then sends
the signal again, some iterations work, some don't).

I also tried registering different signals to different workers (still
using the same handler); same result.
i.e. I tried using (in a separate module loaded through shared-import):

uwsgi.register_signal(1, 'workers', my_handler)

or

uwsgi.register_signal(1, 'worker1', my_handler)
uwsgi.register_signal(2, 'worker2', my_handler)

or annotating the handler with

@signal(1, target='workers')

No dice. I also tried sending the signal from the shared module instead of
the mule, still same result.
Am I misunderstanding something?

(uWSGI 2.0.13.1, Python 2.7, OS X 10.11)

Thanks in advance,

Angelo
