Because of the poor memory management in the compiler, I included 
a modified GC-stub when I compiled the frontend as a library, so 
that it can be used in long-running processes:

You can call gc_annihilate(true) to delete the entire heap.

Obviously you need to keep the library in a separate DLL with its 
own runtime, and carefully avoid holding references to GC memory 
across annihilations.

This technique is working pretty smoothly for me so far.

Also to compile it as a DLL you either have to remove main() from 
mars.d or play games with the C runtime:
