I have tracked down the bad revision by checking out current svn and using
svn update -r command to isolate.

Fix CPU spike when pressing DTMF after agent login.

The problem here is that DTMF was being continuously deferred and
requeued
since ast_safe_sleep is called in a loop. There are serveral other places
in the
code that sleeps and then loops in a similar fashion. Because of this fact
I
opted to not defer DTMF any more, which will not affect the original fix:
