But that shows a case with no pipes connected, using select() as a dumb sleep and ignoring SIGCHLD. In our usage we have pipes connected, and I think select() should return when the child's output pipes become readable due to EOF. I guess something about that might be b0rked on Windows? I see there is an extra helper process doing socket<->pipe conversion (hah, that explains an extra ~10ms at the start in my timestamps)... I can't really follow that code, but perhaps the parent forgot to close the far end of the socket pair, so there is no EOF?
