Hi Michael,

Application code is only reloaded by HUP when your preload_app setting
is false.  Otherwise you have to use USR2 + QUIT to upgrade your entire
process.

This behavior is documented in the Configurator, but not in the SIGNALS
documented, I'll fix the SIGNALS document in a few and disable
expand_path in the launcher scripts.
