std.parallelism: Naming?

[dsimcha]

I'm reconsidering the naming of std.parallelism.  The name is catchy, 
but perhaps too general.  std.parallelism currently targets SMP 
parallelism.  In the future it would be nice for Phobos to target SIMD 
parallelism and distributed message passing parallelism, too.  These 
might belong in different modules.  Then again, std.smp or std.multicore 
or something just doesn't sound as catchy.  SIMD would probably just be 
array ops and stuff.  Distributed message passing would probably be 
absorbed by std.concurrency since the distinction between concurrency 
and parallelism isn't as obvious at this level and std.concurrency is 
already the home of message passing stuff.  Please comment.
