+** Fix session garbage collecting errors
+   When a session is being destroyed by the Guile GC, the session garbage

+   list.
+
+   Now the bug should be fixed.

+** Fix segfaults that occur on session closing
+   When a remote side closing a channel Guile-SSH would fail as the libssh
+   callback that marks the Guile-SSH channel as closed tried to convert a

+   Now the problem should be fixed.
