[For what it's worth, and based solely on experience in the Java world
and to a lesser extent on experience in GNOME land],

XML handling has proved to be _incredibly_ computationally expensive.
While XML can be lovely to conceptually express data in, serializing an
object graph to and from XML, parsing text into a DOM (or whatever)
model, and then the impact of keeping it all in memory to manipulate has
been quite significant.

Usually, XML is either non-optional or worth the cost, but I suppose I
am moved to ask the Bazaar hackers about their use of XML and whether it
might be a pressure point from a performance perspective? I was a bit
surprised at what Alexander noted above.
