Not if you don't want corrupted files. Callback lifetime is determined
by the fileserver, and the protocol requires that clients invalidate
cached metadata when the callback expires. Failing to do this can
result in your cache becoming stale, which in turn can cause your client
to write old data from its cache over top of new data on the server.
