The module name might be 'MinimalLogger', but everywhere else it is known as 
'the stupid log'.

No, I dont think ownership is relevant. Any log file which the zope process 
can overwrite it of little use in proving that your zope process has not been

There is a trick here - it writes two pid files. One is written by the server 
process (as you point out, this one is written very late), the other is 
written by the supervisor process immediately after forking. By default this 
is in var/zProcessManager.pid

You should be able to send SIGTERM to the supervisor process, and it should 
pass it on to the server process. Ive only just discovered that:

a. The signal forwarding doesnt seem to work for me

b. The default stop script doesnt use this pid.
