r14079: I just found the setproctitle library from alt linux:-)
- add set_title hook to the process models - use setproctitle library in process_model standard if available - the the title for the task servers and on connections metze (This used to be commit 526f20bbecc9bbd607595637c15fc4001d3f0c70)
