Approximate number of milliseconds to
run before returning. If 0, then the function will
continually process requests without returning unless an
error occurs.
Details
Note that while service is waiting for a new
request, the process is not interruptible using normal R
means (Esc, Ctrl+C, etc.). If being interruptible is a
requirement, then call service in a while loop
with a very short but non-zero Sys.sleep
during each iteration.
