Fix deadlock in spawn driver on windows
A misbehaving port program that does not read all data written to the port may deadlock the scheduler thread when it calls port_close. The chosen solution was to use the new function CancelIoEx if it exist (Vista) otherwise let the spawn driver wait for a short while (10ms) and then to spawn a thread that will wait for the port program to exit.
