BTW, I have plans to change the internal structure of files again (not urgent). These will probably make access after `Finalize' not crash, but treat the file just as closed and unbound.

IMHO we can easily get such behaviour with current structure. We just need to pre-allocate one "invalid" FDR and change `Finalize' so that a) it does not mess with this FDR b) after finalization it makes files point to this FDR
