I've profiled this before, and the biggst culprit is the parse phase.

We need benchmarks for NQP-rx, especially memory benchmarks.  I suspect there 
are potential optimizations in NQP-rx, but I also suspect that our naive 
register allocator is suboptimal, and I wonder if a lingering GC bug hurts as 
well.

How can we start to write benchmarks to help us profile NQP-rx?
