The current version of telak hasn't fundamentally changed in over a year. There are only two possible causes that I can think of; - gcc 4.x produces different code from gcc 3.x, and that causes the problem. - changes to the kernel caused the problem. Meanwhile I've started telak with 'nice -n 15', to see if that fixes the problem. :-) I also reniced the X server to -10. >> It also happened with cc1 when I was compiling a port.

My desktop's CPU is usually not very busy, unless it= 's running a port compile or a big TeX or povray job. =20 >> In case I forgot to mention it, I deleted and recompiled all ports after >> the 6->7 update to make sure there was no old cruft lying around.
