Summary:                    crash when calling ao2_unlock inside
pthread_timer_disable_continuous
Description: 
When under heavy load we have experienced random crashes (6 times in a day)
at the same point in the code. The load is with about 200 channels, 70
users and making a lot of calls. It was very stable until we started
reaching a certain level of usage.

Use poll() instead of select() in res_timing_pthread to avoid stack
corruption.

This code did not properly check FD_SETSIZE to ensure that it did not try
to
select() on fds that were too large.  Switching to poll() removes the
limitation
on the maximum fd value.
