Encouraging preliminary results implementing memcpy in D

[Mike Franklin]

I had a little fun today kicking the crap out of C's memcpy with 
a D implementation.

Request for help: I don't have a Linux system running on real 
hardware at this time, nor do I have a wide range of platforms 
and machines to test with.  If you'd like to help me with this 
potentially foolish endeavor, please run the program on your 
hardware and send me the results.

Feedback, advise, and pull requests to improve the implementation 
are most welcome.

Mike
