THe pid parameter is declared as 'pid_t' but GetProcessId returns
DWORD - are those types guaranteed compatible.

Also the pid passed into qio_channel_command_new_pid is used
by qio_channel_command_close/abort, to kill off the process,
but this code is stubbed out in WIN32 and this patch hasn't
provided an impl.
