from spawn.c:853:
"The @a stdin_cb may write to @c channel only once per invocation, only 
if @c G_IO_OUT is set, and only a non-zero number of characters."

Though I haven't tested (or don't remember) whether writing more than 4K 
under Win~1 may block... If that's the case, your stdin_cb will better 
be identical to spawn_write_data.

and from spawn.c:853:
"Convinience @c GChildWatchFunc callback that copies the child exit 
status into a gint pointed by @a exit_status."

It took me a considerable time to solve a seemingly simple task, so it 
would have been a shame not to document everything. :)
