Hello Sean Bright, Friendly Automation, 

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

pbx_ael:  Fix crash and 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 protection to reloading to ensure only one ael reload is
executing at a time.
