To me it seems that libxslt is trying to load Saxon extension -- perhaps
it does this during the following code
function-available('suwl:unwrapLinks')
As this extension is not suitable for libxslt nothing is done.

I suppose with advanced filesystem caching available check for existence
of file should be very cheap operation. But if this is concern for you
you can try to delete all calls to
function-available('suwl:unwrapLinks') and corresponding branches in the
code and see if there is a difference.
