Ruby 2 appears to build & run fine... I'm not sure what I'd need to execute
to ensure I run a __sync_* instruction, but messed around with threads &
mutexes without problems.


Interestingly, when I build raindrops with my regular ruby 1.9.3 install,
the generated makefile includes "ARCH_FLAG = -m32", but when I build
raindrops with ruby 2 / trunk, I get "ARCH_FLAGS = -march=i486".  When
built with that flag, Raindrops works fine.
