If I recall correctly, there was a pretty big performance hit for certain 
regexes that include submatches. I think this may have occurred when we 
upgraded irregex to 0.8. I mentioned it on IRC previously, but I don't know if 
I saved the exact test cases. I will check later today. however, I think this 
was an algorithmic problem and not something solvable with compiler 

The svnwiki-sxml extension uses regexes heavily. It does not process 
particularly slowly from a human perspective, but you could construct a long
