The offshoot conversation on locking which I caused probably isnt helpful...

The underlying code use mutexes anyway - or a lockfile and as long as
apache is running it will clean up.  So yes it does work as you said.

When I implemented my sessions I wanted control over the session id and
under no circumstances wanted to use a cookie - I use pure server side
sessions - which cause more hassle, and given that at the time I was not
familiar with the _apache stuff in mod_python and therefore produced a
different locking system for my own file bases sessions.

WRT the FileSession class its best to use the locking as provided by the
_apache stuff - as Grisha says it does a great job.

All that needs to be ensured is that locks are of request duration and
not session duration.

Sorry for muddying the waters!

Cheers,
Barry
