I'm not exactly sure what you're asking, Ara. What happens in this code is
that the HTTP requests are fired off simultaneously, and as they complete,
the callback gets called for each completion, always on the same thread.
(There are no additional green or native threads being spun here.) So
there's no contention and no need for mutex protection. If you wanted for
some reason to run this code simultaneously with unrelated code on other
threads, then of course you'd use the normal thread-safe procedures to sync
this data with your other threads.
