Hello Sean Bright, Friendly Automation, 

I'd like you to reexamine a change. Please visit

    https://gerrit.asterisk.org/c/asterisk/+/16348

pbx_ael:  Fix possible crash and serious lockup issue regarding 'ael reload'

Currently pbx_ael does not check if a reload is currently pending
before proceeding with a reload. This can cause multiple threads to
operate at the same time on what should be mutex protected data.  This
change adds a reload mutex and prevents multiple reloads from occuring
simultaneously.
