I don't really care what is done for MIPS and there is no reason to
find excuses for not having the foresight.  I just present the facts:
if there is no thread register or something equally fast MIPS will be
one of the platforms which will have only a subset of the
functionality of the other Linux architectures and not all
applications will be able to be compiled for MIPS.  That's all.  If
this is fine (e.g., for MIPS on embedded platforms) then all is good.
If somebody wants to use threads and MIPS there is a problem.
