thanks @Trott - I have been thinking of a debugging strategy around this without a way out. This looks like a great plan to me. Only theory that can explain the current behavior (not the failure itself, but the missing debug info) is a race condition between child exit and its pipe flush, and this change is going to resolve that. |
