Regardless of the GIL, it might be easier to consider how the work may 
be divided up in a higher-level language and to introduce the necessary 
abstractions. And a lot of parallel stuff can be done in a multi-process 
model, anyway, as things like make and distcc readily demonstrate.

This is the big question. My understanding was that Mercurial was 
already competitive with, say, Git on performance because of smarter 
decisions about data representations, thus demonstrating that the 
"everything on the metal" school of coding doesn't always guarantee 
superior performance.
