I'll bet that if you read up on the JVM, you'd find most everything that 
CLR does and a little extra besides.  The IBM optimization team is the 
best in the business.  You may argue about some things, but system-level 
software is owned by IBM.

I'm not an optimization expert, but you'll find some pretty cool stuff here:

This is from back in 2000, and it's just scratching the surface.  The 
fact that Microsoft is incorporating technology that has its roots in 
the 90s is hardly groundbreaking.  And this isn't meant as a knock; I 
appreciate your enthusiasm.  I'm just a little surprised that you found 
this such a revelation.
