If you have the hardware resources, have you considered A/UX? I develop all
my Mac applications under A/UX, including XCMDs. If I want an actual
Mac binary, I transfer the source over to LSC.

A/UX is also more stringent in 32-bit clean, no-no memory accesses and
priviliged instructions etc. -- helps keep your app inline for 7.0 and
later releases.
