The reason is MT issues. The Parser is syncronized and thus, only one
instance of parsing can be running at any one time. Having a pool would
allow us to have N number of parsers going at the same time. Note, I believe
this is just the initial parsing of the file into an AST, not the actual
execution of the AST. So, it really isn't a huge performance hit right now,
but will become one later as more and more people put load on Velocity.
