Creates a new child_watch source.
The source will not initially be associated with any GMainContext
and must be added to one with g_source_attach() before it will be
executed.
Note that child watch sources can only be used in conjunction with
g_spawn... when the G_SPAWN_DO_NOT_REAP_CHILD
flag is used.
Note that on platforms where GPid must be explicitly closed
(see g_spawn_close_pid()) pid must not be closed while the
source is still active. Typically, you will want to call
g_spawn_close_pid() in the callback function for the source.
Note further that using g_child_watch_source_new() is not
compatible with calling waitpid with a
nonpositive first argument in the application. Calling waitpid()
for individual pids will still work fine.
