Something changed in our system and we started seeing memory leaks in mhttpd again.  I guess someone 
updated some front end or custom page code that interacted with mhttpd differently.
I found a few memory leaks in some (presumably) rarely seen corner cases and we now see steady 
memory usage.  The branch is fix/memory_leaks 
(https://bitbucket.org/tmidas/midas/branch/fix/memory_leaks) and I opened pull request #55 
(https://bitbucket.org/tmidas/midas/pull-requests/55).  I couldn't find a BitBucket account for you 
Konstantin to add as a reviewer, so it currently has none.

Thanks,

Mark.
