> Below is a summary of the probe's commands
> cmd = 0                                       no finalizable object created, main() does
cpu intensive task forever
> cmd = 1                                       a bunch of object needing finalization
are shoved onto finalize queue
>                                                       also, each finalizer runs only
a short time
> cmd = 2		same as cmd==1 except each finalizer runs cpu intensive task forever
> An example command line for running this probe:   "java Finx 2"
