That's correct: I'm doing the upgrade in stages, and tagging them along the way 
so we can measure each individual change's performance impact. The stages are:

- Upgrade compiler switch to OCaml 4.00.1 runtime (done)
- Move to new cstruct/ocplib-endian API (ongoing)
- Upgrade compiler switch to OCaml 4.01.0+dev snapshot, which should activate 
the new marshalling builtins (not started)
- Install the .cmx files for all packages (not started)

The last three should result in a speedup, and the first one should not crash 
:-) Balraj has tested the 4.00.1 runtime against the TCP benchmarks, and that 
is not affected.  I'm hoping to commit the new cstruct bits today, if all goes 
well.
