That's expensive how? Abort-deferral is (or should be) just toggling a bit in the TCB. Abort is expensive (it has to check whether the bit is set, be able to be deferred, etc.), abort-deferral is not. (For Janus/Ada, if there isn't any significant use of tasking in the program, even the bit-toggling is left out.) Abort-deferral is too common to make it expensive! Randy.
