Wouldn't a specialty engine be excluded from the normal load sharing? By

In the case of IFLs, all those things are run on the IFL. For zIIPs and zAAPs,
that's a different story. Ed's right. There is one and only one instruction
that is disabled on an IFL. Everything else is identical to a standard engine.
Right. And, given enough of them, not all general CPs used by z/OS will
field interrupts either. See the CPENABLE parameter.
