pwd behaviour when new users are added

I just ran into an interesting feature of the pwd module

say I have users fred, ethel, ricky and lucy on my system and I
issue a 'pwd.pwgetall()' this returns a tuple with user
information. Now, while my programme is running I issue a
'useradd gilligan'

if my programme now issues another 'pwd.pwgetall()' or a
'pwd.pwgetnam()' or 'pwd.pwgetuid()' the new user name is not

if I 'reload(pwd)' it still doesn't work if I 'del pwd' and
then 'import pwd' it doesn't work.

What am I doing wrong?

BTW: I have posted here a couple of times on shadow password
issues, and the outcrop of those posts is that I have written
three replacement functions for the pwget*() that include
shadow information in the tuple returned. It works quite well.

Stand Fast,
