Fair enough, and I'd picked up from posts in that past that you have some
pretty comprehensive testing so I wasn't really having a dig at you guys.

I'm acutely aware of testing issues at the moment though - the small trading
firm that I work for was recently bought by a large Wall Street bank for our 
technology, particularly for order execution and electronic trading
machines that just sit there and every day make significant money by 
themselves. Yet, despite our testing, we still role out stuff that 
sometimes has careless bugs and it just plain sucks. Small company, infinite 
drive and 'get it out the door asap' approach to minimise lost trading 
opportunities, and where you know that you can fix a bug quickly and role 
out a new release, is just no longer appropriate or acceptable in a much 
larger corporate environment. 

So testing is an issue much on my mind at the moment :-)
