Done.

Turns out to not be a crash, but it is a real problem.  The driver can 
get into an inconsistent internal state if a connection loss event 
occurs.  Proper fix triggers deadlock due to interdependencies.  

Hackish workaround in place now, and I'm working on a proper fix.  Or 
will be once my head stops throbbing.  The code is needlessly complex 
and interdependent, and unravelling a bit at a time is difficult.

This state problem actually explains a bunch of other odd quirks I've 
seen, so fixing it properly is pretty important.

More progress here, but more work to be done. (Only a problem now if 
device isn't idle when yanked -- if the supplicant is attached, it 
deadlocks still)

No progress here yet.

I'll post another patch set this weekend.
