The same applies to Thread.interrupt().

Interrupts can be cleared or deferred indefinitely, so Thread.
interrupt() isn't a guaranteed way of cancelling a thread which
doesn't respect the protocol.

Much the same goes for the complaint that resource revocation
violates encapsulation: if it's unexpected an interrupt 
represents a pretty violent disruption of control flow.
Of course an interrupt isn't always unexpected, but then 
neither is resource revocation.

Cheers,
