i am curious. given that java virtualises stuff sufficiently, couldn't a jvm implement a many-java-threads-to-many-kernel-threads model where it uses a pool of kernel threads as virtual CPUs to execute java code -- plus uses native threads in a one-to-one model when calling out to native classes? i might be missing something, but this seems to give you the benefits of both worlds.
(plus i think you can reduce the number of stacks in use -- so that you don't require one native stack for each java thread... means less L2 thrashing.)
i'm also curious what functionality the kernel lacks for implementing many-to-many threads. one thing i can see lacking is something along the lines of sun's SIGWAITING (sent when all lwps are blocked).
