Wow, that's unexpected.  I had thought that the connection from the
stunnel process to the rsync process would have been a normal (albeit
local) socket connection.  Perhaps it is not?  Or perhaps there is a bug
that got triggered by this setup.  The way rsync works, it has two
separate processes accessing one socket (one reading, one writing), and
both need to be notified of the EOF.  It sounds like the receiver got an
EOF when reading (and terminated) but that the generator did not get
told about the EOF when waiting around to write.
