Actually, TLS works on OS X: dmd emulates it, while ldc has 
native TLS using undocumented OS X APIs.  I'm unsure of how 
full-fledged the support is on those other issues, but I believe 
the big issue is that loading multiple shared libraries is not 
supported, as that will take more work:

If you want to talk to someone about getting more of shared 
libraries working, I believe Martin is your man.
