[Red5] rtmpt 'too many files' error

[Interalab]

We may have solved the problem on Ubuntu with too many files open error 
(or actually Joachim's suggestion did) :

http://jira.red5.org/browse/APPSERVER-87?page=comments#action_10506


Please reply if anyone knows why we *shouldn't* use this method to 
resolve the problem.

Thanks,
Bill
