Perhaps we speak slightly different versions of English, but I was
merely alerting you to the fact that the idle callback runs in the main
program loop, in case you didn't realise that. Clearly you do, which
is fine.

Incidentally, to see if you have recursive locking have you tried
recursive mutexes to see if that exhibits the same problem or not?  If
they don't your search is narrowed considerably.
