  Applied without troubles, it passed the regression tests, so this looks fine.

  Without the patch, Red Hat 7.3 gcc -g -O2, Duron 1200 no memory debug, best of 4 runs:

paphio:~/tmp/XML -> xmllint --timing --repeat --noout ~/XML/doc/libxml2-api.xml 100 iterations took 9626 ms

paphio:~/tmp/XML -> xmllint --timing --repeat --noout ~/XSLT/tests/XSLTMark/db1000.xml 
100 iterations took 4262 ms

  With the patch:

paphio:~/XML -> xmllint --timing --repeat --noout ~/XML/doc/libxml2-api.xml 
100 iterations took 8994 ms

paphio:~/XML -> xmllint --timing --repeat --noout ~/XSLT/tests/XSLTMark/db1000.xml 
100 iterations took 3878 ms


approximately a 6% and 9% improvement on this platform and for those tests,

    thanks !

Daniel
