Ensure fork13 better scales on standard machines.

fork13 is a test prog backported from upstream mainline:
5fdee8c4a5e1800489ce61963208f8cc55e42ea1. However, it produces flooding
outputs that may cause syscall output log too large (30GB+!!); also
10e+7 times fork is too time consuming, 10e+6 should be valid enough
to reproduce the issue and it takes less time (~3min); if the test
fails, it would put an error msg, this might cause flood error msg in
output log as well, so I make it return immediately when a failure
occurs.
