This would be the only job running.

as for other types of jobs under ps aux there's only
udev,dbus,acpid,sshd,wicd running.

Now with this oom-killer I'm
hitting this on an imac9,1 with
gcc (GCC) 4.5.0 20091029 (experimental)
2.6.32-rc5-00083-g04ea458

On my other machine macbook pro ati chipset
(same system pure64)firefox seems to be going a lot farther
than on the imac(doing this in the past I think this takes a good
45min to compile).

the macbook has:
gcc (GCC) Cross-LFS 4.4.1.20090722) 4.4.1
2.6.32-rc4-00039-ga3f6f2e
