On SVr4 compliant systems, cdrecord uses the the real time
class to get the highest scheduling priority that is pos
sible (higher than all kernel processes). On systems with
POSIX real time scheduling cdrecord uses real time
scheduling too, but may not be able to gain a priority
that is higher than all kernel processes.
...
nice --18 mkisofs -R /master/tree
on systems that don't have UNIX International compliant
realtime scheduling.
Cdrecord runs at priority 59 on Solaris, you should run
mkisofs at no more than priority 58. On other systems, you
should run mkisofs at no less than nice --18.
...
Now, the man page may have been revised for 1.11aX, but that's what it
says on 1.10.
