Interesting idea. Yes, in principle we could implement a JVM where all
java.lang.Thread instances are green threads, and all IO operations
are nonblocking, just like GHC runtime, and this will allow Java
programmers to write code in the easiest way (just new Thread()
everywhere) without performance penalty.
