I was able to test that the memory consumption is because logger
thread can't process all the messages that get posted. Maybe I was
just lucky obtaining that output of "memory show allocations" before
asterisk locked, and it has nothing to do with this patch.

I'm currently testing with my patch (logger_repeating.patch from issue
https://issues.asterisk.org/view.php?id=15973), and it seems to help
with memory issues.
