> This issue is related to SSHD-35.
> The change implemented in that issue causes the EOF to be propagated to the shell, but
because the inverted shell has to pump between the SSH streams and the Process streams, the
EOF never makes it to the OS process.
> The cause is that ChannelSession.handleEof() calls shellIn.close(), but shellIn is not
directly attached to the process. In fact it's InvertedShellWrapper.pumpStream() that copies
from the shellIn to the process, and that doesn't handle EOF.
> I can't see a obvious fix.
> I've put a bit of a hack in that does what I need (and proves that this problem is as
described), but it really is a hack...
