I'm fine with this improvement but curious as to how the user would be
able to set this property in the MC. Is there some module that's spsed to
do that?? Sorry; I'm missing a link (no, not the missing link).

Remove async message receivers ------------------------------

Srinath was working on http://issues.apache.org/jira/browse/AXIS2-1363,
and we here at the hackathon got involved in a discussion about
asynchrony on the server side. To make a long story short, we decided
that it's overkill to make the user specify an asynchronous
MessageReceiver in order to get the behavior of spawning a worker
thread to do the actual business logic.
We'd like to instead have a property on the MessageContext (which can
of course be set on the operation or service) which specified whether
or not to prefer separate threads. If this "preferSeparateThread"
property is TRUE, then we will spin off a separate thread to do the
business logic *if* we're using another channel for the response - if
we're using the backchannel (WSA anonymous or no WSA), there's no real
point in spinning off a thread since the current thread is most likely
going to have to wait around for the response anyway.
We propose to put this logic in AbstractMessageReceiver.receive(), and
to head towards deleting AbstractAsyncMessageReceiver and all its
subclasses (simpler code is better code!) by deprecating them for 1.3.
We can actually delete them in a release or two.
(Interesting code tidbit - the RPCMessageReceiver and the
RPCInOutAsyncMessageReceiver are, code-wise, just about IDENTICAL
except for their parent class and whitespace!)
