I actually ran into the same issue when I first used this...
Another thing to look out for is FileReference. I haven't tested anything
outside of the following case, so I don't really know the rules surrounding
the cause.
Well, if you define FileReference inside the same function body that you
call download()/upload() - it will fail. You get an I/O Error... In this
case, when the function defining FileReference is finished executing, the
reference to the FileReference instance is gone, so it should have a
reference count of 0. This leads me to believe that the issue is some how
linked to garbage collection. What is strange is that this doesn't cause any
other classes that have asynchronous methods to misbehave (Loader,
URLLoader.) Stranger yet, callbacks to IOErrorEvent.IO_ERROR are still
invoked. I've yet to run this with the Profiler to see what is going on...
