JRuby is a mixed-mode interpreter and compiler (to JVM bytecode) similar 
to how HotSpot works. The compiler doesn't compile all Ruby syntax, but 
it compiles more every day. What it can compile, it does compile in a 
JIT fashion as the code runs.

It's likely we'll have a 100% complete compiler to bytecode along with 
the current "very high" level of compatibility before IronRuby achieves 
either, but I'm the only one working on the compiler at the moment.
