Yes, it's true that NFSv4 has open and close operations, but filehandles
are still used a great deal outside of that, and clients are still
allowed to assume that the same filehandle always refers to the same
object.

http://www.ietf.org/rfc/rfc3530.txt, section 4.2.1:

	"If two filehandles from the same server are equal, they MUST
	refer to the same file."
