"Dispatch", as in "Grand Central Dispatch", Apple's answer to Life, the
Universe, and Everything.
Basically GCD is a threading mechanism combined with C/C++/ObjC/ObjC++ language
extensions for "blocks" (lamdas) that allow you to do fine-grain thread
scheduling inline, like this (going from memory so I'm sure the following code
won't compile as-is):
dispatch_async(dispatch_global_queue(), ^{
/* code that runs in a thread */
});
Blocks can also be used in place of callback functions in most places now as
well.
