Summary:                    Using pattern match in a hint causes deadlock under
described conditions
Description: 
When using the following hint, most "dialplan reload" commands will lock
the system up. Once in deadlock, existing sip conversations will continue,
new sip connections will fail. sip show peers will look normal.
exten => _4040XXXX,hint,Custom:phone${EXTEN:4}

I have about 25 phones subscribing to this hint, and creating the "virtual
hints", on initial load all is well, reloads lock the system.

I have included attachments with core show locks and a bt trace of a
running thread to show where the deadlock is occurring.
