Can you please repeat this AMA at a later date and at a time of day when people on the west coast of the USA are awake? Alternatively, please keep it going for a few hours if you would be able to be so generous with your time! Thank you for doing this!

Do you also answer questions about the standard libraries? This is not so much a C question as a library question:

I'm wondering if Apple's Grand Central Dispatch ever made it into a more integrated role in C's libraries, or if it will forever remain an outside add-on. And whether there is anything else at that level (level in the sense of high versus low level) in the standard libraries that plays such a role, that I should read up on instead of GCD.
