There is lots of subtle trade-offs involved (eg. less PHP parsing,  
smaller memory footprint, but more fopen() calls) and it is hard to  
predict how these level out.  Let's not make claims and just  
benchmark it?

We did some preliminary benchmarks and noticed a 10% performance  
cost.  This cost was not caused by fopen() but by the way variables  
were handled.  This might be less of an issue with this patch.

It's well worth exploring this further, IMO, but rather than guessing  
we should collect factual data.
