This is expected.

This is not a TileCache problem. 

The problem is, specifically, that Python running within mod_python
can't access to the URL that you have configured.

This typically means that something about your configuration doesn't
allow this type of access. Perhaps it's a firewall rule, or something
else. 

You can try testing with a python command line: typing:

import urllib
urllib.urlopen('http://labs.metacarta.com/wms/vmap0').read()

If you get the same error: great, fix that, then move on.

Unfortunately, this usually doesn't happen: usually people come back and
say 'it works on the command line, but not in TileCache.'

At that point, it's a problem with your machine/mod_python, which I
don't know how to solve.

However, it's not a TileCache-specific bug, so you'd want to look for
'mod_python urllib timeout' in searches, rather than anything TileCache
specific.
