This was effectively dead code, since the places that tested it could not be reached after we entered the on-exit-cleanup routine that would set it. It seems to have been a leftover from a design in which error abort would try to send fresh commands to the workers --- a design which could never have worked reliably, of course. Since the flag is not cross-platform, it complicates reasoning about the code's behavior, which we could do without. Although this is effectively just cosmetic, back-patch anyway, because there are some actual bugs in the vicinity of this behavior. Discussion: <15583.1464462418@sss.pgh.pa.us>
