[jifl:] I would have thought the assumption is that it is up to the *caller* of Cyg_Interrupt::attach/detach to disable interrupts if that's what's needed. And in most cases the interrupt would be unmasked after it's attached (unless there are chained ISRs, but that's for the user to worry about). Perhaps the solution you really want is documentation?
