16K blocks shouldn't give to much extra overhead because of the
reparsing, so the figures should be pretty close to optimal for
xmllib.

I don't feel threatened.  I was the first to create an XML parser for
Python, and nobody can take that away.  :-)

I looked hard at the XML spec when implementing it, so I feel pretty
confident that it is reasonably close.  I did some more work after 1.5
came out, so my current version is even better (though not necessarily 
faster).
