# Note about non posix support

On non-posix platform the lib have some limitation.

When the master process receives a signal, the propagation to children processes is done manually on known pids instead of the process group.

SIGHUP is of course not supported.

Processes termination are not done gracefully. Even we use Popen.terminate(), children don’t received SIGTERM/SIGBREAK as expected. The module multiprocessing doesn’t allow to set CREATE_NEW_PROCESS_GROUP on new processes and catch SIGBREAK.

Also signal handlers are only run every second instead of just after the signal reception because non-posix platform does not support signal.set_wakeup_fd correctly

And to finish, the processes names are not set on non-posix platform.
