You may skip the `watch -n 2' to see a one shot.  The watch
command overwrites the same screen with the next shot every
2 seconds.  If you record this in one file you may have a
look with the `cat' command or `more -fr' ... only the time
between two screens are very short.  Nevertheless the first screen
of your attachment looks like:

USER       PID %CPU %MEM   VSZ  RSS TTY      STAT START   TIME COMMAND

which is fully correct.  You see here the main program VDR with
the pid 19349 and the associated threads of the that pid.
Nevertheless: the signal handling has to be checked, mainly for
SIGALRM to be sure that the singal will be delivered to the main
program and not one of the threads.  In other words, does moving
a cutmark work with my signal patch?
