 From myself or Andrei? I don't recall such.

There's nothing inherent to D or druntime that requires a multithreaded 
operating system. After all, a single threaded OS is a multithreaded operating 
system that simply returns an error when a call to create a new thread is initiated.

We did something similar with the GC info, i.e. RTinfo. I think the same 
technique could be use for TypeInfo.
