We need a one-stop reference book/site which details all available JVM
options for all OSs. The current info is scattered through online books and various links which makes it difficult to find general or specific info. For example, it is very hard to find any info about the '-XX:+OverrideDefaultLibthread' option.
Documenting _all_ -XX switches is a bad idea, since we'd like to be able
to change/delete them at will if they're "not well known" to customers.

Closing as WNF. If demand resurfaces, it'll provoke a new CR.
