Charles,
Yes - all three streams will now be closed. Previous to 7082769, when
any of the streams calls close(), the underlying filedescriptor used get
closed out via the native close0() call.
A list of Closeables is maintained by FileDescriptor.
regards,
Sean.

With Alan's assistance, we have a better implementation in place
where we avoid the use of counters and instead cycle through a list
of shared closeables when a FileDescriptor is being shared.

Hi Sean,
If we have 3 FileInputStream which share the same FileDescriptor, and
one of the FileInputStream calls its own close. Will other 2
FileInputStream close?
I see fd.closeAll is called in the close of FileInputStream, I guess
it will close all the things which shared the same fd.
