We should not use main thread's CFRunLoop, because it doesn't have one.

CC'ing Dave and Dmitry, because they dealt with callOnMainThreadAndWait before.

Stray unused local variable.

I would reword the second sentence as "Misusing this can easily cause deadlocks."

Need a period.

Can't we use something that's actually a pointer? We could use a local variable to name it. Like this, for example:

    void* arbitraryNonZeroPointer = loaderRL;

> +    CFRunLoopAddSource(loaderRL, bogusSource,kCFRunLoopDefaultMode);

Missing a space after the comma here.

We would normally use !loaderRL, right?

How about calling the global variable loaderRunLoopObject instead of loaderRL?

I just realized I'm reviewing the moved code. Oops.
