> AcceptHeaderDelete.fromString() is called for every invocation.  This drives calls \
> to string splits and some regex tools that start to show up in profiles as taking \
> up a notable amount of time.  Since the content for the Accept headers will remain \
> within a fairly bounded set, we can cache the parsed content and improve \
> performance. Here's a patch with a simple solution.  Really I think there's a \
> better way to do this.  Presumably, there are other headers where the same thing \
> applies.  We can handle those on an individual basis or we can come up with \
> something more generic that can be used by all HeaderDelegates.
