When DD emulated by HHH calls HHH(DD) (its own emulator)
it tells HHH to emulate itself again in recursive emulation
until aborted because DD is calling its own emulator.

When DD emulated by HHH1 calls HHH(DD) (not its own emulator)
it tells HHH to emulate itself again yet not in recursive
emulation because DD is NOT calling its own emulator.
