I posted to the mailing list a few years back with a Deferred class that
can log what callbacks were called, what result they returned, etc. It
would be very easy to add callback timing information to that. You'd just
insert a callback into the chain of any deferred you wanted to monitor to
have it

Hello,
I have a question about the "best practices" on making callbacks and making
sure you don't hog the reactor.
So you pass a deferred to a client, who attaches a chain of callbacks that
might probably do some CPU intensive stuff. How should one guard for that? The
obvious solution to me fo
I will try to make a proper tutorial out of them - please don't spread that
file around, I'll remove it at some point.

Hi,
I was wondering what's the recommended way to initialize a "complex"
twisted application. Typically, let's say I have an application which
needs to create a couple of "heavy" objects, each of which may create
mysql db/tables:
class MyApplication(object):
def __init__(self):
