Hi!
There seem to be some problems with top:
top - 10:19:24 up 4 min, 3 users, load average: 0.74, 0.48, 0.21
Tasks: 58 total, 2 running, 56 sleeping, 0 stopped, 0 zombie
Cpu(s): 55.1% us, 6.4% sy, 0.0% ni, 0.0% id, 38.5% wa, 0.0% hi, 0.0% si
Mem: 1031424k total, 72840k used, 958584k free, 8804k buffers
Swap: 1953464k total, 5452k used, 1948012k free, 34860k cached

...while compiling kernel, 50%+ time is spent in gcc, but top does not
show it, or it shows it with something like 3% :-(. Same problem seems
to be in 2.6.10-rc3... Does anybody else see that?

I can't say that I can see any difference between 2.6.10 and tip-of-tree.
In fact 2.4 does the same thing: cc1 is either not shown at all or is shown
as taking just a few percent CPU. Occasionally it blips up to 50% or more.
Presumably cc1 just doesn't run long enough for it to register. How fast
is your CPU?

It happened in 2.6.10, too... Okay, probably I have just too fast
CPU. Sorry for the noise.
