Do we really want to add support for this? There's general agreement on
www-dom at w3.org that MutationEvents are something we want to move away from.
Specifically, the use-cases that they do meet, they don't meet well and they
are frought with problems. Mainly, they are inherently non-performant and
invite crashiness. 

A relevant thread from www-dom:

An alternate proposal on public-webapps that addresses both the performance and
crashiness issues:
http://lists.w3.org/Archives/Public/public-webapps/2009AprJun/0745.html

There are some good use-cases for these types of events, but the current
incarnation of MutationEvents is something noone seems happy with (not browser
vendors or web developers).
