whitequark a6ae254796 Si5324: update to free run from XA/XB, with CKIN1 having priority. 2016-11-01 16:01:24 +00:00
whitequark b30734a105 runtime: fix a race condition with async RPCs. 
session.rs has code like:

    while !rpc_queue::empty() {
        try!(process_kern_queued_rpc(stream, &mut session))
    }

    // A

    if mailbox::receive() != 0 {
        try!(process_kern_message(waiter, Some(stream), &mut session));
    }

If both an async and a mailbox RPC (async or large sync) are posted
at point A then they will be processed out of order.
This commit fixes the issue by flushing the async RPC queue before
posting any RPC to the mailbox.
