We already have seen this issue on some cocoon applications ; most of
the time, that was due to intensive use of xpath "document" function
with. We observe that using saxon as xslt processor genrerally solved
that issue.

Most of these issues has been resolved for us doing that ; some are
always present but I did not have time to further investigate yet.
