Until we know whether the expense is the execution or the compilation,
we don't know which problem to solve, and there is a real possibility
that this will all need to get ripped out to support include/exclude
later -- at which time it will be perceived as a regression.

I don't mean to sound obnoxious here, but if CPU is an issue, you need a
better server. Have you actually looked that the CPU utilization on a
modern server? It usually isn't very high. On most servers, the disk is
the real bottleneck.

I begin to suspect that we may not be building the RE correctly. In
abstract, the RE processing should be completely overwhelmed by the seek
and stat overheads here.
