And your SSLeay version?

The SSH server is a multi-threaded application, by default SSLeay is not
thread-safe.  Rather than gear SSLeay towards any particular threading
package, Eric Young provides a means for multi-threaded applications to
supply their own locking callouts when they need to make SSLeay threads
aware.  The pt_initialize() function loads DECthreads-based functions
into these locking callouts.

The pt_initialize() function is part bss_mst.c, which is a module I wrote
as part of SSL support for the OSU HTTP server.  I thought bss_mst.c had
been rolled into the standard SSLeay distribution, but I may be wrong.
(pt_initialize should logically be in a different file that the rest of
bss_mst.c, but I wanted to minimize the number of new files to present
Mr. Young with).

Bss_mst.c, along with the rest of the SSL shim for the OSU server is
available at:

    http://kcgl1.eng.ohio-state.edu/www/preview/tserver_ssl_v3a.zip

Having said all that, I built a version of the SSH server with the lock
debug trace enabled and it seems the only locking is in SSLeay's random
number generator.    While it is only using the locks in 1 module, this
is enough to warrant including pt_initialize() call in the main program.
