An alternative would be to link to a custom library that
implements the pthreads ABI, but stubs everything out in a way
that makes sense on a single-threaded microcontroller.
I wanted to do that once for another project. I never got it to
work for unrelated reasons, so I can't say how well the D runtime
handles it, sorry. It's probably an easier approach than
maintaining your own fork of the runtime, though.
