Socket exceptions aren't in the standard exception hierarchy (M2Crypto issue)

    On a related note, M2Crypto's exceptions are direct children
of Exception.  If we add NetworkError, there will be a better
place to put them.

    Currently, you have to catch, at least,

both of which can be raised by socket operations if
M2Crypto is installed.   I'm not sure what errors the
stock SSL module raises.

(I'm running stress tests on a dedicated machine in a colocation
facility.  It's examining 11,000 known spam and malware sites right
now.  This exercises the error handling, forcing many unusual cases
and logging the problems.  That's why I'm discovering all these library
