That's easier said than done ;)

Making druntime compile as a shared lib and making it support multiple images
is the easy part. Modifying DMD to output the ctors/dtors properly is much more
difficult than it sounds.

The current solution outputs the ctors/dtors by manually outputting byte codes:
https://github.com/D-Programming-Language/dmd/blob/master/src/backend/elfobj.c#L3183

This is why I was saying we should just add some(or one special one) pragmas
that will allow this to be done in the front end.

Wish I knew how =/
