I was also going to ask if the proposed message:

  warning("-XX:+UseVMInterruptibleIO is obsolete.");

was adequate or should also mention future removal? It is also unclear 
whether "obsolete" means "the flag is useless and ignored" or "the flag 
shouldn't really be used, but okay if you insist" ;-)
