If autoplug_continue_cb() and activate_group() are executed on separate
threads, then using recursive mutex is not different from normal mutex...
doesn't this still cause the probelm as in comment #12 ?

I thought that changing the order of {set-state, allow-state-change, unlock}
into {allow-state-change, unlock, set-state} would be OK.
(I thought that set-state itself must not necessarily be protected by the
lock.)

Maybe I don't fully understand the problem.
Sorry to bother you many times due to a bit;) poor quality of my code.
