HI Andreas,
I am sorry to hear about this issue, and it is unlikely that there is any way
to debug it. A hung process doesn't respond to debugging, either!
The best approach is to kill one of the processes using "kill -QUIT" and seeing
if it leaves behind a diagnostic file in $HOME/Library/Logs/CrashReporter/.
Then at least, we may find out what routine it is hanging in.
The only other idea I had is to disable "App Nap" system-wide to see if this is
causing the problem. See:
http://www.defaults-write.com/10-9-disable-app-nap-in-os-x
I don't know why this would affect non-application processes, or why it would
present an issue in 10.10 if it wasn't an issue in 10.9, but it's worth a try.
I will see if I can reproduce this on my copy of Yosemite as well.
Best,
-Greg
