[IronPython] Resolver One 1.4 beta - with IronPython 2.0

I beg to differ...
Ultimately all undelying clr's (ms/mono) rely heavily on p/invoking so  
it really boils down to who maintains the "low-level" bindings...  
Ultimately, without pinvokes you wouldn't be able to accomplish  
anything...

If I was able to get mmap working on Linux/windows/macosx x86/x64 in  
one day then I'm sure it can't be that much of a problem...

Beside managed runtimes like python/.net/java were never about being  
platform agnostic, just about being "less" platform specific...

I believe the official term is:
"write once, debug everywhere"...
