Subject: Guile reconnected (but not debuggable (yet))

Or the importance of EOL. Switching to a transaction queue for
communication with the Scheme process means that i had to care about
sending eols in the queries... Guile was waiting for ever reading a
metacommand taking a variable number of arguments. Argh: this has
taken me a few hours -- i'm getting old.
