That doesn't mean anything. The classic Unix way of doing things like this
is:

 - open a (temporary) file.
 - unlink (delete) it.       <-- from here on the file is "invisible"
 - do your stuff
 - close the file            <-- as soon as the file is closed it's inode
                                 can be reused by the OS.

This is  nice use of the semantics of Unix/Posix unlink: a file will stay
arround as long as there is a file descriptor pointing at it.

Most likely not - Zope uses Python that very likely uses '(3) mkstemp'
or a similar libc function. 
Two _possible_ solutions (after checking that '/tmp' realy sits on a
tight partition): 

   - move '/tmp' to another partition (it should be possible by:
     'cp -ar /tmp  /opt/tmp && ln -s /opt/tmp /tmp')

   - start your Zope like this:
     $ export TMPDIR=/opt/tmp 
     $ /etc/init.d/zope start     # or whatever your zope startscript is ..
