But why would that be a good idea?  It seems to me to be a bandaid that
guarantees misbehavior in the infrequent-notification case.

The real question here, which this doesn't advance us towards solving,
is why is the CallNamedPipe call sometimes failing (or at least taking
longer than it seems it ought to).
