Nice! If you don't want to wait five seconds after saving your file, you could stick a call to your reload-check (without the sleep or the loop) in srv.arc at the point a request comes in:
(def handle-request (s (o life threadlife*))
(if (len< (pull dead srvthreads*) threadlimit*)
(let (i o ip) (socket-accept s)
+ (atomic (reload-check ...))
(++ requests*)
though of course you wouldn't want to do this on a server that had a lot of requests coming in, since it would do the check on every request.
I found in practice that 5 seconds we fast enough, I would save the file, switch to browser and refresh and it would be there. Of course 5 seconds is the worst case - 2.5 seconds would be the average.
