Mimimal runtime library

[Lukas Lädrach]

Hi everybody,

I'm looking for the absolute minimal set of files in phobos i _need_ to run a full featured D application.
This means that I don't want to have any unneeded functionality in these files, only the framework to make the language complete.

For me, this would mean:
- Object and Interface base 
- Type info
- Exception handling
- Startup system (ctor/dtor handling, __main, _main)

Only as stubs
- GC
- System interface
- Stdc lib
- Thread

Has someone an idea? Walter?
