Unlike the previous race, I've seen this one before.

The test checks, in particular, whether "strace -c" shows a reasonable
value in "seconds" column, by invoking nanosleep with 1 second argument.
On very slow systems, that syscall may take arbitrary amount of time.

I wouldn't like to relax the regexp as it would make the test result less
reliable.
