I just started looking at this. Has anyone gone through a process to
enforce/engage/initiate the use of thread safe coding techniques?

This is based on the assumption that we desire/need to allow the
concurrent running of web agents. I say assumption because I had gone
through a period of time where we had numerous issues with semaphore
locks (almost all caused by HTTP agents) that I would typify as
coding/logic problems. Most of those have been cleaned up. However, we
just had another 'blip' and conceptually this bothers me. If we have a
web agent that misbehaves (for whatever reason) it has the ability to
impact all other web agents/applications.

Our applications are 99% Domino. We only have a few functions that are
Notes based. When the HTTP side goes black or brown I get all kinds of
noise about the server locking up. It has taking some convincing to get
some developers to step up and clean up some questionable practices.
However, it has me thinking architecturally about the risk of being
synchronous and then I also have the nay-sayers who can't believe that
Domino has this single thread risk.

It would seem that if you don't have these coding problems or an over
busy server the gain may not be great. It also seems that this is not
an easy to solve and manage solution based on what I'm reading.

Tools?
Practices?
Experience?
Is the pain worth the gain?
