Dear Cygwin heros, I've been happily using cygwin to run buildbot slaves for several years. However, periodically they hang at the end of executing git. It kind of smells like SIGCHLD isn't delivered somehow.
I shrugged it off as 'I'm using an ancient copy of twisted, it's my fault' for a long time, but recently updated to latest twisted, and it is still happening; today I came in and both of my windows buildbots are hung with it. While sniffing around at the edges of the problem, I noticed that the hung process would resume if I simply ran strace on it and then hit ^C to terminate strace. Here's the output of cygcheck and strace: http://kegel.com/linux/cyghang/ Older context at https://github.com/buildbot/buildbot/issues/3801 I'll surely hit this problem again soon; what other info should I gather? My next sensible step is to use an up to date version of buildbot's slave (I'm running a very old one at the moment), but it seems kind of fishy that strace could wake the process up.
