Asynchronous Operations

@defer.inlineCallbacks support

If you want a deferred async method, just use defer.returnValue():

@route("/",Http.GET)
@defer.inlineCallbacks
def root(self,request,**kwargs):
        val1 = yield db.query("SELECT ....")
        val2 = yield db.query("SELECT ....")
        defer.returnValue(val1 + val2)

This is standard Twisted functionality.
