Wait a little bit after fork()ing the lockers to give them a chance to 

get started before trying to ptrace(ATTACH).  Otherwise, the traced
process doesn't seem to resume properly upon ptrace(DETACH) and on the
next pass the ptrace(ATTACH) just hangs forever, causing the test to
time-out.

XXX The failure-to-resume-properly might actually be a kernel bug that
we need to follow up on.  But for now, let's make the test work as
intended.
