Synopsis: fix for a core dump in /bin/sh dotrap()

State-Changed-Why:
The patch in the PR (modified) has been applied - eventually.

Normally the PR would be put in feedback state to await testing,
but there does not seem to be any way to do that here (the
bug has no known trigger) and since the fix applied is more or
less the same as what the PR requested, I am simply closing this
PR instead of going via the feedback route.

I did not include the error() call in case the problem would
have occurred, if it is the race that I think would cause this,
that would be inappropriate.  Instead, we simply force the
result when this particular race is run.
