What that means is there's a ton of work to do on dmd, and implementing TLS 
three times is a waste of effort. dmd will eventually have to match what the 
default C compiler does on the Mac.

I'm also not terribly concerned if TLS access is slow, only that it is correct. 
This is because a program that depends on fast TLS access is badly designed, for 
several reasons.

And lastly, if you wish to work on the OSX TLS, I do appreciate the efforts. I 
think it can only help. Please look at how clang is doing it, if it is doing it.
