There is a potential race between a concurrent call to FD.initIO, which calls FD.pd.init, and a call to FD.Close, which calls FD.pd.evict. This is solved by calling FD.initIO in FD.Close, as that will block until the concurrent FD.initIO has completed. Note that FD.initIO is no-op if first called from here. The race window is so small that it is not possible to write a test that triggers it.
