Nonsense.  I will synchronize on a temporary file so that the
child will not die due to a not yet installed trap handler when
the first signal is emitted.
Would be nice to have some shell support for signalling the parent
that the child is now functional, a pipe(2) is much easier than
going through temporary files, but of course not a bash bug.
Sorry for the noise.
