I an using code that I wrote using threads.deferToThread(), I wondered
if it was blocking the reactor maybe, so I tried just using a plain
deferToThread() call. Here's the code (without all the protocol stuff,
it's executed when data come in.
m = utils.createMessage("toto", "hello")
print "Sending %s" % m.toXml()
the TCP no delay option is turned on like I said before, the weird thing
is that I have the same thing, all my msgs get sent in big blocks.
Either the TCP no delay doesn't work, or the reactor is getting tied up.
I don' t get it since I'm running the blocking code in a thread, the
reactor should have nothing to do.
I know that I'm not returning a deferred, I am in my real code though,
but this is just "debug" code.
