As a side note to this discussion, there really ought to be some sort
of threaded IO architecture that's standard in, say, Cocoa or
CoreFoundation. Most of the Obj-C socket wrappers use CFSocket
nowadays, but many of them, AsyncSockets included, need to bend over
backwards a little to keep data flowing (and not block!) while attached
to the main run loop. I have yet to see an open-source alternative
which has taken the plunge and created its own IO threads [1]. This is
probably due to the fact that, in order to do so, you really need to
write a lot of supporting code to get thread-safe queues (sure CFArray
has some heuristics to determine when its being used as a deque, but if
you know ahead of time that you're going to be using it as such, you
can do a little better) and write some non-trivial code to message run
loops (not necessarily the main run loop so -[NSObject
performSelectorOnMainThread:etc.] is out). In short, there really is a
need for an updated MiscKit for the community. The Omni groups
frameworks are great, but there's a LOT of stuff in there which is IMHO
a bit over-engineered and a little crufty. Anyone else feel the same
way? Should we create a new MiscKit, or just keep using nifty classes
from all these different authors?

[1] I say open-source because I wrote a threaded socket class for my
company which has quite a bit of supporting code. (It's all fun and
games until you want your threads to not retain the socket class.)
Perhaps one day it'll become open-source, but I wouldn't hold my
breath.

Check out the AsyncSockets stuff, it is very easy to use and feels
VERY "Cocoa".
