Each signal has its own purpose. Delivering SIGTTIN where there is no tty input for background process does not seem a good idea. For instance, tar itself does not handle neither of these signals (it doesn't have to, anyway), so when delivered any of them it will simply stop, as their semantics dictates (see man 7 signal). That's perhaps not what you want. Regards, Sergey
