So what?  If the memory is wanted for something else, it will be
reclaimed.  How does this differ from any other filesystem?  In
fact, this memory seems to me more likely to be effectively reclaimed
than that holding other vnodes, because (unless you've done something
to stop it) the server process is, unlike in-kernel holders of vnodes,
eligible to be paged...
