The test asks zdaemon to run the `touch` command with umask 666.
Therefore nobody (except root) should have write access to the file
`touch` creates. The failing
self.assert_(not os.access(path, os.W_OK))
asserts that write access is in fact not allowed.
But note the "except root" in the above: if someone is running as
root, there's no chance this can work. More recent versions of
zdaemon start the test with this check:
if os.getuid() == 0 :
self.fail("""
I am root!
Do not run the tests as root.
Testing proper umask handling cannot be done as root.
Furthermore, it is not a good idea and strongly discouraged to run zope, the
build system (configure, make) or the tests as root.
In general do not run anything as root unless absolutely necessary.

Good advice :-)
