Python Library Reference 11.9 poplib - POP3

Presently says, "One exception is defined as an attribute of 
the poplib module..."

Recommend adding:

"The POP3 library is built using the socket package and 
socket exceptions are not caught by POP3."

In fact, this might be a good sentence to add to most 
Internet packages.

I needed this info to figure out how to have a POP3 
connection timeout on a message download.
