How exactly do you invoke screen?  Does "setsid" work for you?  Does
"nohup"?  IIRC, bash also has an option for controlling whether background
processes are terminated on exit...

What is the error message when screen runs as SYSTEM?  I suspect it's a
fifo permission issue...

As for hanging does it consume CPU at all?  Try attaching to the process
with strace and seeing where it hangs.

If you wish for others to try reproducing your behavior, please post the
"minor changes" you mentioned above (as a patch).

If there's any real truth it's that the entire multidimensional infinity
