I'm no PDF expert, but fro what I've read of the specs only global
objets and something to build the xref table at the end of the file
should be kept in memory, most of what is in each page should be
disposable...

Any idea on how to really free up unneeded memory, and keep only
what's needed to finish the PDF ?
