Bummer.
So the only viable workarounds are 1) don't use Thread.interrupt (nor,
things like Future.cancel, which in turn use Thread.interrupt) with
NIOFSDir, or 2) we fix NIOFSDir to reopen the channel AND the app must
make a deletion policy that keeps a commit alive if any reader is
using it. Or, 3) don't use NIOFSDir!
