There is a fascinating talk by Cliff Click "A JVM Does That?" At the end he shares some opinion about what should be done by JVM or OS and what should change.
I remember a talk, where he was also talking about hardware. It does not seem to be this one. For example, a time register would be useful. Syscalls like clock_gettime are too slow. CPU info like cycle counts fail with dynamic frequency scaling.
