(Assuming that indeed there's no way of using sockets in a non-blocking
fashion - I'm totally ignorant about that) maybe having a little process
created with multiprocessing would be simpler & more portable, for you,
than using threading? I guess a single one is sufficient, so the
overhead shouldn't be significant, even on Windows. Then, at every
iteration of the main loop, the main process could check, from a shared
Value (or Array), if there's something to open.

(untested, sorry if I wrote something stupid)
