In the new gspawn.[hc] files in the devel version of GLib, there's a
flag where you can choose whether you want to do the grandchild deal
or do the waitpid() yourself. These functions will probably end up
replacing gnome_execute_async(), they are a bit more flexible, have
nicer error reporting, and can set up stdin/stdout/stderr pipes for
you.
