     The implementation is very close to the phtreads implementation, the reason for
     using MPServices is the fact that these are also available under OS 9. Thus allowing
     for one common API for all current builds.

     As soon as wxThreads are on a 64 bit address space, the TLS must be extended
     to use two indices one for each 32 bit part as the MP implementation is limited
     to longs.
