As I recall, this was a JDK internal and undocumented jetpack used by 
code such as the Solaris ucrypto provider. It's unfortunate that it 
found its way into answers on StackOverflow and code in important fields 
starting to rely on it.

I think it would be best to start a discussion on panama-dev as the 
desire to invoke syscalls that promise not to block is understood there.
