Several posters have reported issues when calling Flush Close and
Dispose on the stream they get from GetInputStream.

Worth remarking for any readers, it is recommended not to call any of
those methods against the entry stream.

Even without calling Close/Dispose the .NET GC may finalise the outer
stream while still using the entry stream. Believe this has been fixed
in 0.85.5 - worth desk checking.

"There is a flaw in the dispose method of ZipFile also which isnt
checking for disposing before closing streams. The f
inalizer for ZipFile can indeed be removed as Daniel states.  There is
nothing for it to do once you correct the flaw above."
