Memory leak in cherryssl.py

I was hoping that maybe someone could see an obvious reason why this
code causes a memory leak.  This is an ssl wrapper for cherrypy, a
small python webserver.  When I use it, every request consumes a bit
more memory and the process just grows and grows.  When using cherrypy
without the wrapper it works fine.  My first thought was that it might
be a problem with m2crypto since without the wrapper the problem goes
away, which is why I am sending this to the list as well as the author
or sslcherry.

The test code is very simple, it just returns a string.  You can see
the wrapper code (it's very small) at:

Following is the code I use to start cherrypy using sslcherry:
-----------------------------------------------------------
from cherrypy import cpg
import sslcherry

class OT:

  def process(self):

    return "OK"

  process.exposed = True

cpg.root = OT()
'''cpg.server.start()'''
sslcherry.start(configFile='ot.conf')
