It was a special-case hack to fix a special-case need. It was extremely 
easy to implement (about 2 hours work) and has been very successful in 
fixing that need. Everything else that anyone has talked about is at 
least ten times as complicated, and doesn't seem to offer significant 
advantages.

It's really easy to come up with over-engineered solutions to these 
sorts of things.
