Jcon is to Icon as JPython is to CPython.  While Icon's coexpressions are
spottily implemented across "real machines" <wink>, via excruciating
platform-specific assembler to fool the C stack, Jcon simply implements them
on top of Java threads.  So the JVM doesn't really enter into it for them
(no more than the PVM enters into my ancient thread-based coroutine pkg for
Python).
