looks like it should work.

minor nitpick: In my case, the loop was provoked by an
DISCONNECTED/CONNECTED pair immediately after resume. Also, I don't know
what system instability you're referring to - maybe a buggy wireless
driver can be stressed by repeated reassociation? If that's the case,
though, i'd say the system's already unstable.

I agree it would be nice to do something a little more sophisticated,
but this works at least.

thanks,
