[Bf-taskforce25] Complete Rewrite

[Campbell Barton]

It 'could' be true, you can JIT compile higher level languages to run
as fast as low level languages like C.
Mono for example can do JIT compiling taking advantage of SSE at runtime.

Though I have been using Netbeans recently (and eclipse before that)
with (Sun's JVM with hotspot), and I get quite frequent hangs due to
garbage collection and weired errors that leave me wondering weather
the applications internal state is messed up or not...
And Netbeans is from sun who wrote java!
- So Im quite happy not to be tried to java with its sluggish jvm.

Interesting article how unity3d moved their UI from Mac-Cocoa to
Mono-C# with their own widget set.

Even though almost any combination lua&c, java&c++,  C#&c, perl&D
etc... could be made to perform acceptably if we were careful.
Currently blender devs know mostly C & Python, its unlikely we'll
switch any time soon.
