Oh yeah, this is all beside the point if either
a) The signal handlers are already thread-safe (after all, the CONNX
guys called it on a different thread. Did they change anything in the
actual signal handlers, that we know of?)
b) The signal handlers *can be made* thread-safe fairly easy (no need
for re-entrant, but any variable access needs to be synchronized)
If they are, then you can fire the signal handlers on a separate thread,
and just be done with it.
