[slime-devel] Reconnecting, and slime-buffer-connection.

Temporary buffers created by Slime will save the current connection in
`slime-buffer-connection'. If you disconnect, and then connect again to
the same Lisp process, the connection stored in the
`slime-buffer-connection' variable will still point to the previous
connection which was closed by the disconnection.

If we keep track of the connections we disconnected from, and look
during slime-connect if the connection attempt is actually a
reconnection (determinable by comparing host, and PID of the Lisp
process, I think), we could make the above scenario work.

How would you be going to implement this?

  a) We could grovel all buffers, and just reset slime-buffer-connection
     if appropriate.

  b) Slime-connections are network processes. We could add a level of
     indirection (putting the process in a struct, say), and make
     connections reconnectable this way.

The first option is probably simpler, while the latter may be
cleaner. FSVO "cleaner", anyway.

What do you think?
