You probably couldn't find an explanation of Twisted threads due to the fact 
that Twisted is implemented almost exclusively without using threads at all.  
Aside from the large library of protocol implementations, this is one of its 
main selling points. ;)

After reading my comment above, hopefully it is clear what is awry in this 
code.  You cannot use sleep() in a Twisted application and expect anything to 
work well.  Instead, a scheduling primitive is provided, 
reactor.callLater(delay, function[, *a[, **kw]]).

However, rather than using the low-level APIs of twisted.web directly, you may 
be interested in using an implementation of this idea which already exists.  
Take a look at <http://divmod.org/trac/wiki/DivmodNevow/Athena>.  The tutorial 
builds up a web page which does something very like what your code seems to be 
attempting.

If you pursue the Twisted version, keep in mind the web-dedicated Twisted 
mailing list you can use as a resource: 
<http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-web>.
