Um - I do it all the time. My mailer of choice is exmh. I've run exmh,
netscape, audio/video clips seti@home, all while burning CDs with no
difficulties. (Mind you, I do have a dual-CPU SMP system.)
The trick is to run "cdrecord" as root so that it will set itself with
high "realtime" priorities for its processes, and use a temp disk file
for the CD image. cdrecord seems to automatically try to set realtime
priorities, at least when built from the port.
I found piping mkisofs into cdrecord didn't work well for deep
hierarachies - mkisofs sometimes hit a place where it'd spend an
inordinate amout of time spinning and cdrecord's buffer would empty,
then bye-bye CD-R blank. System activity or lack thereof made no
difference - it's something inside mkisofs.
