This is extremely good news.  I may (finally) have to get a mac. :)

Interesting. From the last comment from Walter at the bottom:


 But the Mach-O has no such special sections.
 
 I think I've found a way to do it, but it would be better if the mac 
 was fixed to handle that like other systems do.



I wonder what's that way of doing it.

I think that mac can do this using function calls, but I can't find the 
man page right now.

There are pthread calls for TLS which are implemented for OSX.  But 
however it works (I haven't looked into it), it likely isn't as 
efficient or easy to deal with as the __thread storage class on other OSes.

It won't be as efficient. But that really doesn't matter at this point - 
accessing global variables in a tight loop is a bad idea anyway. TLS 
just has to work. It can be optimized later as OSX improves (which it 
must, as TLS is going to be a bigger and bigger deal as time goes on).

I don't agree so much with this, TLS can be useful is some occasions 
but should be used very sparingly in my opinion, it should be used 
mostly for the infrastructure, not by the end user.

TSL is an evolution of global variables and still has many of their 
drawbacks, if possible one should pass the variables explicitly, often 
with some care, and maybe grouping them into structure it turns out to 
be easier than one thinks, and the effort costs little typing.

There are things where TSL can be very useful, and I use it for example 
to make the scheduling interface nicer, but I think that with good 
design those cases are few...

Encouraging wide use of TSL is bad in my opinion (not that you are 
doing it, but one might interpret it like that).

If decent support for TLS is not there, then programmers will use 
regular global data instead, which comes with a whole raft of threading 
problems.

I plan on doing a brief writeup on it in a future blog if it works.

Very exciting! Thanks, Walter!

Do you know whether OSX releases will be produced for D1, or just D2?

I've had my fingers crossed that you were working on this, and I'm very 
happy to see that the progress is so swift :o)
