Hi,
I've recently started employing the opportunistic multiplexing feature, and
I've come across what seems like a bug.
Here's how it goes: in Fedora Core 5 I run the Gnome terminal application,
and open two terminals (two tabs). In the first terminal I initiate an ssh
connetion that becomes the master for multiplexing; in the second terminal I
open a second terminal session to the same host. After this, I background
the master on the first terminal via "~&"; even though the process
forked,
it still had the I/O/Err descriptors open according to /proc/$PID/fd.
Now, the funny part - if I run ssh in first terminal with the same target
host, it opens the connection through the master, but I cannot do anything
since the input seems to be hijacked by the backgrounded master. This does
not manifest itself if I do anything else locally, eg running ls or vi.
Furthermore, after goning through the input-hijacking mention above, the
backgrounded master won't terminate even after all connection through it
finish (even after killing the defunt session which has no input).
Also, this is reproducible.
