    Correct.

    Not having garbage collection has surprisingly not gotten in the way
    so far, so it's not even on the radar anymore.  There are other means
    available for persisting objects past the lifetime of the parallel
    context, and you could always do an @async.call_from_main_thread if
    you want to have the main thread's memory allocator (and thus, GC)
    kick in.

    At one point, all these tests passed, just to give you an idea of
    some of the facilities that are available:

    (I haven't removed any of those facilities, I just haven't spent any
     time on them since switching over to the async socket stuff, so I
     can't comment on their current state.)


        Trent.
