[libdispatch-dev] I missed the intro message ;)

[Matt Wright]

Hey Shantonu,

Yeah I read his email. I just must have misparsed it.

On a similar note to some of the other things I mentioned. When the  
project page talks about the kernel support, are we just talking  
kevent/kqueues here? Or are there more darwin kernel level things at  
work. I'm looking more for the limitations when targeting Leopard,  
rather than porting to non-Darwin, and moving towards using  
libdispatch linked to an application without needing to load kexts/etc  
on Leopard.

I also found it interesting that you built it so it could run without  
blocks. I found when writing WW that life was ever so much easier  
using blocks to my advantage during implementation.
