[plug] POP goes the threading

[Tom Hallam]

The performance will depend upon the length of the transaction.  For a
small email file the pop transactions are quit short.  With a short
transaction the overhead of doing a fork is likely to be a significant
part of the total transaction time.  

You'd really have to test this with multiple users and large mail
boxes to get a good idea of how it would work in real life.  The whole
idea of threading/forking a daemon is that the system does not block
for all users whilst one large user hogs it.
