Glad to hear it. I've got some spare cycles (day job starts again 8 
July.) :) I was about to start up on this, but if someone is doing it, 
I'll wait. My own thinking was to do

1. Check out Ruby 1.8.6 from SVN.
2. Compile with GCC 4.3.1 with the "gcov" coverage analysis and debug 
options. I only have an AMD64 dual-core and 4 GB of RAM running Gentoo 
Linux, not a buncha VMs with every conceivable environment. For other 
environmental reasons, I compile *with* threads.
3. Run all the test suites and benchmark suites (someday, we really 
should merge those.) :)
4. Post the code coverage analysis, test suite results, and tracebacks 
for any crashes "somewhere". I've got "oprofile" working, so I can also 
post profiles if anyone cares.

I'm definitely going to do the benchmarks; this started out as a 
profiling exercise on Rubinius. :) A Rakefile would be nice, but I am a 
terrible Rakefile writer -- for some reason, I can't do "DRY" Rakefiles. 
I usually end up just defining a whole bunch of Ruby methods to make a 
sensibly factored set of code, which seems somehow "un-Rake-like." :)
