This is caused by pthread_cancel effectively throwing a not-specifically-identifiable C++ exception into the targeted thread, which, if it is not rethrown, terminates the process entirely. This is rather "impolite" behaviour, we would say. But thread cancellation is *always* busted, and we should simply not use it where unnecessary. It's particularly unnecessary when what we *actually* need it for is, err, interrupting a poll(2). That can in turn be achieved by simply listening to more stuff in the poll, namely, a pipe, which we send a character to when needing to stop the thread. While looking at this code, we also investigated whether any of the poll() madness is required, or was even *ever* required. Curiously we found in the XNU kernel source code that the thing about needing to listen to POLLHUP is probably *correct*, but switching it to POLLRDNORM should not have made any difference at all. We've left a FIXME to look into that further because what's written here is super janky. |
