s/initiated/contained/ i.e. all sessions are contained within a thread.
The other thread does not do anything with libssh2.

Only one thread does. However I am getting login failures with error
message "Failed getting banner". Looking at another mail thread
(http://www.libssh2.org/mail/libssh2-devel-archive-2010-06/0243.shtml)
it seems the problem went away after compiling with -D_REENTRANT. I
tried this but it didn't help. Unfortunately I can't access the
associated ticket as libssh2 trac is down.
