[Twisted-Python] Re: Stackless Python/Twisted example

Don, you need to read the code along side the slides.
I will probably be giving a revisted version of the
talk in early May.

I will annotate the example in the week to follow.
However I need to change the code somewhat so it is a
wee less confusing to a newbie and gets rid of a
design flaw concerning daemonisation. 

With the current programme, if you hit the processor
fast enough, you will get back 404s. These really
should be 500s. This is not a problem with the
technique but with my simple minded implementation of
the WS-BPEL specification that warns of race
conditions associated with certain activities.

Although fine for my purposes, I should conduct two
sets of tests

1) More feature torture tests where I test non-trivial
message exchange patterns.

2) Performance tests. Test against
- Apache ODE
- A Stackless /Twisted solution that does not spawn a
server instance in a tasklet
- A pure Twisted solution
- A Twisted solution that uses inlineCallbacks.

Cheers,
Andrew
