This problem is quite annoying. I already tried to investigate, and it seems to me that occasionally SIGCHLD signal is NOT delivered to emacs when the child process terminates. I tried to continue a little bit, but got lost very quickly in cygwin's signal implementation (hey, that's *really* complicated code). I tried strace and the only thing which caught my eyes were these lines: 33 40372399 [sig] emacs 16900 wait_sig: processing signal 20 389 40372788 [sig] emacs 16900 wait_sig: Got signal 20 48 40372836 [sig] emacs 16900 sig_handle: signal 20 32 40372868 [sig] emacs 16900 sig_handle: signal 20, about to call 0x201405D0 3900 40376768 [sig] emacs 16900 setup_handler: couldn't send signal 20 115 40376883 [sig] emacs 16900 setup_handler: good.
