Yes, I had already commented that out. :-)

Actually, most of the delay is due to various sleep() calls in various
places(!). I fixed most of them in GNOME bug #344825:
With the these in place, with the dhclient hack and dhclient.conf fixes,
and another patch to networkmanager I haven't had the time to clean up
yet, performance is now pretty zippy: it only takes about 2.5 seconds to
associate, down from 10 or more...
Good to know that this will make it into the next release. Thanks!
