I agree there's too much marketing hype surrounding GCD, but neither the CLR nor the JVM can jump through that particular hoop.

It's interesting. For the little I have seen (and I was only able to give it a quick glance) it includes syntactic support for multi-threading being built into their Objective-C compiler. Are they forking the Objective-C compiler?

  Apple has been shipping forks of GCC forever. In the future they won't have to fork clang because they own it.

  Chris Lattner's first paragraph here talks about that a bit, although it doesn't give a timeframe for when the gcc implementation will make its way back to the main distribution: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2008-August/002670.html http://lists.cs.uiuc.edu/pipermail/cfe-dev/2008-August/00267... Although, there's a comment by Johannes Fortmann here that says that the code has been available in an svn repository since at least September 5, 2008: http://mooseyard.com/Jens/2008/08/blocksclosures-for-c/ http://mooseyard.com/Jens/2008/08/blocksclosures-for-c/ "If you check out the llvm-gcc svn trunk, you’ll find all the code there (you can even build your own llvm-gcc with working blocks)."

  They are investing in heavily in llvm which they hope to replace gcc with in the future.
