Bacon --- I suspect that listing directories like this is infrequently done and even = less frequently verified. I don't recall ever doing something like this before = that depended on an accurate directory listing. So the issue may have happened = to others but likely went unnoticed. Had I not had parallel processes needing= the exact same file list in order to function properly, I never would have caug= ht it. I'll try and construct a minimal, reproducible test case so it can be explo= red more easily. --=20 You are receiving this mail because: You are the assignee for the bug.=
