This was my intention, but i never noticed that the shell would end the `rtprio' command at the pipe operator. ;-) Anyway, it seems that the rtprio is more religious on my side, while the usage of team(1) is indeed what makes it safe to burn CD's while running full multi-user. Its user-level multi-megabyte cache does a good job in prefetching data off the disk. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
