If the server's process pool (used for actually running the diffs) fails repeatedly, assume it just can't be started and crash the whole server so a process manager can clean things up and totally start over. You can retain the old behavior (where the server keeps trying to start a new process pool if the old one is broken) by setting the
RESTART_BROKEN_DIFFER
environment variable totrue
.Fixes #42.
