Hi,

Not sure when this started happening, but I wanted to report it. I'll
start bisecting in a day or two if noone else has gotten around to
looking at it:

$ echo "int main(void) { while(1); }" > test.c ; gcc test.c
$ time ./a.out & sleep 2 ; killall a.out
real    0m2.008s
user    0m4.014s
sys     0m0.002s

Seen on POWER5 and PA6T, haven't tried anything else yet.
