That is right. With my variant one given thread may stuck forever
that does not change.
The big advancement that the stuck thread does not hold any lock,
so it cannot make the full milter-greylist stuck.

In my case I guess (I did not verified) the spamd (spamassassin) is stuck
and it holds the corresponding thread in the milter-greylist
which than holds all the other working threads.

I think in addition to, with the assumption I made before,
if I would kill the spamd process,
the corresponding thread would continue to run
releasing all the resources it is using at the end.
