The execute procedure is defined at the top of gui.tcl as:

	proc execute {cmd} {
	    exec -- $cmd &
	}

Anything which is run via "execute" should get run in the background.

Hmm. For some reason, a few commands are using exec (without the &)
rather than execute; r.sunmask is one of them.

AFAICT, the list of incorrect cases is:

	r.out.gridatb
	g3.createwind
	g3.setregion
	g.setproj
	d.monsize
	r.sunmask
	r.shaded.relief
	r.le.pixel
	r.le.patch
	r.le.trace
	v.segment

I'm not sure how this occurred; I've attached an update.

The d.mon commands are run with arguments. They should complete more
or less immediately, and so shouldn't need to be run in the
background.
