jistone on #systemtap had me run this systemtap script:
probe process.begin {
printf("hello\n")
}
And we found that I was getting the same "Device or resource busy" when running
the stap script at the same time as "strace df". jistone thinks that this is a
kernel/utrace bug since this was reproducible down to systemtap 0.9.9 on Fedora
11 kernel 2.6.31.12-172.2.22.fc11, but not reproducible on Fedora 13 kernel 13
2.6.33.5-112.fc13.
