Attached is roughly the test case I was using when I was working on
this before - it broadly mirrors one things that the OpenStreetMap
site does when answering requests.
Basically it creates 100 GPX files, each with 10000 points in - in
real life each one would be streamed back to the client but in this
test we just go on to the next one.
With libxml-ruby 0.3.8.4 this grows rapidly to a resident size of
about 650Mb to 750Mb (total virtual size is about 50Mb more than
that) and with my patches it is stable at a resident size of
about 35Mb (about 95Mb total).
