This was sent to me directly, anyone willing to act on it? (I don't have
the CPU cycles right now).

I think may be useful to add this question:
2.30. Why do I get "No space left on device: Failed to create global
mutex" ?
Because mod_python has get all the available semaphores of your os.
To avoid this error on GNU/Linux do
#ipcs (to see all locked semaphores)
#for i in `ipcs | grep "www-data" | awk '{print $2}'`; do ipcrm -s $i;
done
www-data is the user which runs apache[12] (in Debian)
In this way you release all resources locked by apache[12]
If you want to increase the number of available semaphores append
kernel.sem = 512 32000 100 512
to your /etc/sysctl.conf
and do
#sysctl -p
------------------------------
Some of the content has benne derived from
http://www.modpython.org/pipermail/...ril/017858.html
You can change anything you want of course 
Thank you for the great work
(even if configuring mod_python in debian is painfully... )
