Perhaps someone else would be better.  I have no way to test mesh
right now, and still do not understand this code too well.

Hopefully the vif-counting work would help with dealing with
your scenario, however...

Also, could you try with my patch(es)?  Part of the problem with the old
code is that if you added mesh second, you would not be in AP mode anymore.
I think that part will be fixed now.  There may be other issues remaining,
however.

Thanks,
Ben
