[python-ldap] Proper timeout handling

[ondrej.kolin at gmail.com]

Hi guys, 

How should I properly use timeout in basic operations like
.get_naming_context? 

Imagine this code:
l = ldap.initialize('ldap://test.xyz.com')
l.get_naming_context() 

But this times out on some internal TCP connection timeout, which is
pretty long, can I use a shorter one? How?

Regards,
Ondrej
