It's true that the MacOS has provided limited thread support since 7.5, but:

"The Thread Manager is an addition to the Macintosh Toolbox that 
enables concurrent programming for true multitasking within an 
application. The Thread Manager supports cooperative and preemptive 
threads of execution at the application level, not at the system 
level."

I would not presume to know exactly how the lack of system level 
support for threads impacts a port of 5.005 to the current MacOS, but 
gather from Rich's post that it is a deal breaker. A more interesting 
issue is why MacPerl doesn't support threading at the application 
level in any case (at least as far as I know)?
