It is, kind of. Depends on which version you're using...
Newer versions automatically start a timer and call those functions
on the necessary intervals.
(See tcpip.c:tcpip_thread() if your version already does this.)

However, it isn't really necessary to stop the timer since it doesn''t
run that often.
