Unless you're running Unix on the Mac.  I guess that a Mac
will suffer similar interrupt overhead in this case.

Perhaps the Apple engineers added this feature to help reduce
interrupt overhead when running heavyweight operating systems.
Do you run Unix on your IIfx?  Can you compare serial port
performance: Unix vs. MacOS?  Just curious...
