Well, it's not uncommon to start a program with a reduced set of environment
variables, including a limited, hardcoded $PATH, so something like
os.system("ls") cannot be tricked to run an ls outside the
system-controlled, "safe" directories.
On my machine, "env -i sh" starts a shell without $PATH. Bash seems to
default to a builtin search path in that situation (/bin and /usr/bin, I
suppose).
But reducing $PATH is one thing (and fairly common); removing it is another.
And I'm not sure that programs are expected to cope with the absence of
$PATH; just because it's /possible/ to remove it doesn't mean it's legal.
I don't know anything about web servers and Zope. Sorry.
