The SIGHUP handler was implemented to allow admins to send SIGHUP to a running
Asterisk process to reload the configuration.  However, doing the actual reload
in the signal handler itself is a very bad thing to do, because the reload
process includes calling non-reentrant functions such as malloc/calloc/etc.
If Asterisk is running in the background, then the reload will happen
immediately.  However, if running in console mode, the reload doesn't work
until something is typed at the console.  That sort of defeats the purpose,
but I don't see an easy way to get around it at this point.
