Both are LLVM extensions. They're not specific to Mac OS X, but they 
currently only work on Mac OS X. It's the only platform where they're 
implemented.

As I said, it should be possible to use blocks from D, if one really 
needs to. I'm also looking at this long term. Hopefully we can use D on 
iOS one day, that would mean pretty much only use Apple specific API. 
Also creating a GUI applications usually requires to use platform 
specific API's.

I prefer to write cross-platform code as long as it's possible. But have 
no problem in using platform specific API's if that enhances the user 
experience.

I have not used GDC myself in a long time. But on all the talks I've 
seen by Iain Buclaw, he mentions TLS on Mac OS X.

Great.

If you're lucky you can use the same debugging code for GDB and LLDB. 
Since LLDB is supposed to have many of the GDB commands as aliases.

On the other hand LLDB is built as a library so if you really wanted to 
you could integrate it directly in the plugin.
