[erlang-questions] perform a function on a fixed time interval

[Joseph Wayne Norton]

One technique is to flush the erlang process's mailbox after returning  
 from compute().

You can find an example inside this erlang module:

   http://github.com/norton/gdss/blob/master/src/brick_clientmon.erl

Look for flush_mailbox_extra_check_status().  The flush is needed because  
net_adm:ping/1 can take several seconds if the target host is offline.
