  Hum, the problem is that the parser drives the data consumption.
And unless adding check for the condition set by xmlStopParser() in
a lot of places it's hard to make an instantaneous stop.
  Still bugzilla it, it should be relatively simple to find at least
a few crucial spots where this condition could be tested to exit faster.
Resetting all the callbacks is a bit extreme that can probably be avoided
(especially now that parsing contexts can be reused).
