Yes, you can stub the thread and mutex interfaces. You will of
course not be able use that or any part of the library that uses
threads but you will be able to get to the main entry point and
run a single threaded D program.
This is something we would want with the druntime API change, a
stub that people can use when they don't need the functionality
or as a starting point for implementing your own version.
