there is class of problems (e.g. some java programs) that have THOUSANDS of threads, each representing an active aspect of some object. How do you put an rlimit on that without either 1/ stopping the program from working or 2/ allowing thousands of threads to exist but not screwing other users.

Does the JVM actually expose thousands of threads to the OS, or does it actually do its own M:N threading internally based on its execution model? My impression is the latter, exposing threads to the OS only when it needs them to consume kernel or CPU resources.

I think it exposes all threads to the OS. I think "green threads"
was its own threading. You should ask -java, though.
