  Okay i fixed this in CVS. Basically global variables are now
only read from the stylesheet and copied/evaluated within a hash table
in the transformatio context. It significantly improved cleanness 
by making the stylesheet read only and the speed by avoiding walking
a possibly long list (very long in the case of DocBook stylesheets).

  I think the patch won't be useful anymore but I keep it as a safety.
