Please review a revision to the work on remove a dependency on
FileInputStream, FileOutputStream, and add cleanup of closing file
descriptors in FileChannel.
The previous version was too aggressive in removing the finalize method
and was considered to be insufficiently
For compatibility with previous versions, the close method will be
called when the FIS/FOS is unreachable
only when FIS/FOS has been subclassed to override close() or
finalize(). In other cases, the cleaner is used
to make sure the FileDescriptor is closed.
Relax FileInputStream/FileOutputStream requirement to use finalize
