As far as I understand this it's vlock-main which locks (and
unlocks) the screen, not xautolock, which only calls a locker
programm.

My understanding is that it's vlock-main which unlocks the screen
but does not exit for some reason.

I did this 14 times in a row now and the issue did not occour.

Actually I have almost no clue about programming/debugging C.
Now vlock-main does not exit again:

Ciao, Gregor
