Ah. Damn, still this problem!!
I have seen this in a few occasions, and fixed some loopholes, see also 261779.
There must be something left. It's libs/threads/dynamicthreads.cpp.

There is the d->threadRequested safeguard (mutex protected) to avoid requesting
a thread twice from the pool. Additionally, transitionToRunning() (mutex
protected) should return false for a second thread, avoiding to call q->run in
::run(). I must miss something, but I dont know where.
