Note that on platforms where GPid must be explicitly closed
(see Spawn.closePid) pid must not be closed while the
source is still active. Typically, you will want to call
Spawn.closePid in the callback function for the source.
GLib supports only a single callback per process id.
On POSIX platforms, the same restrictions mentioned for
g_child_watch_source_new() apply to this function.
This internally creates a main loop source using
g_child_watch_source_new() and attaches it to the main loop context
using Source.attach. You can do these steps manually if you
need greater control.
Sets a function to be called when the child indicated by pid exits, at a default priority, G_PRIORITY_DEFAULT
If you obtain pid from Spawn.async or Spawn.asyncWithPipes you will need to pass G_SPAWN_DO_NOT_REAP_CHILD as flag to the spawn function for the child watching to work.
