[OpenSIPS-Users] Orderly shutdown

[Bogdan-Andrei Iancu]

OK, let's do a "back to school" when comes to binary representation and ops

Decimal 15 (what you set for initial) is 1111, so all bits (index 0-3) 
are set to 1, to true. So, when you set (to value 1) the gflag with idx 
"1" , nothing will be actually changed as it is already 1 :P
