For whatever reason, when I ported my application to Gnome2/GTK2 this
stopped working. I needed to (synchronously) run a simple program and read
its stdout to a buffer. For some reason this started to fail sporadicly
with "interrupted system call" messages...
So, I dug up the API documents and the GLib helper function g_spawn_sync()
was just what I needed...
