Safe to delete apparently stale / aged 'spool/sync.' directory?

[Bron Gondwana]

Yes, it's definitely safe to delete wheneven the server is shut down.  We remove it as part of the startup script at FastMail, just in case something crashed.  Both sync_server and sync_client will create it if necessary.  You can probably remove it safely, but if Cyrus is running and using replication there is a theoretical probability that a new process will start up with that PID and decide to use the directory!

(pretty theoretical for us, we've gone for large PID space for a few years now, so they don't get recycled very fast)
