The llvm codegen is certainly easier on the eyes ;)

When I started porting my library though, I fumbled around with a bunch of  
compilers and build commands trying to get D/C++ interop to work right.  
xcode's default compiler seems to work nicely with dmd, so I went with  
that. Other combinations where giving me strange linker errors.


As far as the runtime code, I understand most of what's going on, but I'm  
still confused about the purpose of ThreadDSO, and what these are for:
  pinLoadedLibraries()
  unpinLoadedLibraries()
  inheritLoadedLibraries()
  cleanupLoadedLibraries()
