  Unlikely - it doesn't do that much cleanup when going down:
1) saves at all player files who are currently on line.
2) saves out any unique map information.
3) saves out some small amount of other data.

  Now this obviously depends on the system, but in my cases, I'd say that from 
the time the process receives the hup signal to it exiting is less than a second.

      what I can see, the crossloop scripts are pretty basic except

  yes - that is the main advantage of the crossloop scripts - the restart on crash.

  I'd imagine it wouldn't be too hard to have the crossloop script write out a 
/var/run/crossfire.pid file, and keep updating it as it restarts the server (or 
maybe just have crossfire do it itself, as then it has all the configure 
information and might have a better idea where to write it).  Then at least the 
stop functionality is easy to do.

  One could of course do this with pkill/pgrep, but there are potential issues 
if there are other process that might have crossfire in their name (eg, 
usernames or whatever else).
