Every time we think we know a good upper bound to something (i.e. 
"nobody will ever need more than 64k of memory"), it turns out that 
limit is wrong.

There's great value in writing code which continues to work until it 
runs out of some external resource (i.e. memory, disk space, whatever).  
Eventually, somebody will want to do some calculation which you 
previously thought was absurd but turns out to be useful.

I don't use Python bugnums very often, but when I do, I'm really happy 
they're there.
