     7Python documentation states that the _`os.spawnve` function is NOT thread-safe on Windows_ and that the `subprocess` module should be used instead.
     8
     9I hence suspect that a thread that is spawned on reload makes a memory violation and causes a segmentation fault which kills off the server.

     11I propose that `autoreload.py` be refactored to use a thread-safe implementation either by the subprocess module or by other alternative implementation.
