----------------------------------

Matt-

Going to close this.  I hadn't realized that we'd been compiling with Debug Threads on.  When I went back and looked at the make diff, that was the difference between the two versions.

I'm about 98% certain this is the culprit.  Hopefully this may help someone else out.

> Not sure exactly best way to reproduce, but upgraded Asterisk 11.4.0 to 11.5.1 and immediately saw a 10x spike in CPU usage, with no other changes to the system itself.
> System has around 800 peers and 30-50 concurrent bridged calls.  Under even moderate load, the 11.5.1 system spiked to 2 full cores, where before it was running about 20% of one core.
> Reverting the system caused everything to go back to normal.
