Perhaps one should add some kind of emergency timeout (example for 20
sec):
for (i = 0; (i < 20) && (parent_signal == 0); i ++)
sleep(1);
Then one can be sure that at least the boot or any other CUPS restart
does not block the system totally. But this is only a workaround. Please
check especially whether in the case of a blocking "sudo
/etc/init.d/cupsys restart" the CUPS daemon is already listening
("lpstat -p" or printing from other terminal) or whether really the
deamon itself is blocked. If the daemon is always listening in such
cases the emergency timeout would help.
Please report your results so that we can post an upstream bug report.
