 If I remember correctly (it's been a while...), LinuxThreads didn't 
 work properly with threads which relocated their stack. Also, it used r2 
 as a pointer to a thread-local data structure, whereas for the Mac OS 
 thread this register needs to be free for use as the TOC pointer.

 I wanted to use threading in SheepShaver, so I wrote a replacement 
 threading library that didn't have these limitations.

 Bye,
 Christian
