Message-ID: <FA995870-CA62-42E9-B398-8CFB97249C42@raeburn.org> (raw)

By "threads" I meant "threads or helper subprocesses"; we don't *have* to introduce threads to Emacs right now if it would be too complicated for this one little task.
That said, I do hope we can go that route, as I can imagine other things that might be improved with careful use of threads. For example, file access on a slow or unresponsive NFS server blocks the thread trying to do the I/O... but if that's not the thread managing the display and checking for ^G, maybe we can make it appear interruptible to the user, or do redisplay as needed while waiting for the file I/O to finish. (POSIX has an async I/O API that could help too, but I'm not sure if it's portable enough yet, and again the glibc implementation appears to just spin off helper threads.)
Ken
