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. -- Parag Patel To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
