I haven't investigated a lot on Harmony. I just know that they have poor
performance currently (probably their jit is still not in production,
but could also be due to non-optimized gc and class lib). For the class
lib, classpath has a nice VM interface. I don't know if Harmony has it
too. And the pros of Boehm GC is that it is really to integrate it in
existing projects (proof is I've done it in one day for vmkit). I'm not
aware of an interface for the GC of Harmony.

Not at the moment, but patches welcome ;-)
