I now think I know what's causing this, but I don't have a clean patch yet.

Once we are within INPUT_CHUNK near the end of file, 
xmlParserInputGrow and xmlParserInputBufferGrow will
be called from every GROW (and always report they can
read zero bytes).

For a test I appended 2*INPUT_CHUNK of '\0' to the input buffer
in xmlParserInputGrow once xmlParserInputBufferGrow
returns zero. This eliminates further calls and mallocs,
but I assume it will break quite a lot (when more than
one entity is parsed).
