Hi Vincent, thanks for the report, you are right. I removed some stuff
From the threadutils that I thought was unused, but in fact we checked
for the weird exit message:


of the SyncRunner thread. I have to admit that this is one of the last
areas I had not dared to touch/understand so far. But a special exit
message is still needed or we will never exit our "infinite"
threadutil.exitnotifymonitorloop(). I have fixed this in the below
commit in the next branch. We still use a special exit message, and
return from the exitnotifymonitorloop when the SynRunner thread exits.

Let me know if this is now fixed in "next".

    Exit "infinite" monitorloop when SyncRunner thread exits
    The huge UI rework patch removed some obscure logic and special handling of
    thread exit messages. It turns out that this was in fact still needed as a
    specific exit message of the SyncRunner thread signified the threatmonitor
    to quit.
    We will want a nicer machinery for this in the future I guess, but fix the
    eternal hang on exit by reintroducing a special exit message for the
    SyncRunner thread, and return from the infinite monitor loop if SyncRunner
