You can have a cron job do "/usr/sbin/logrotate someconfigfile" as often 
as you want. Just make sure someconfigfile has reasonable parameters for 
things like size so it won't be doing rotation and compression unless 
needed. To get an idea of resources used when no rotation is needed just 
do something like "time /usr/bin/logrotate someconfigfile" when the size 
argument is met and then do it again right away. Here is what I get when 
the asterisk logs don't need to be rotated:

real    0m0.002s
user    0m0.001s
sys     0m0.001s
