[Spambayes] Outlook plugin missing msgs

Just FYI.  My machines have often been under very heavy load the last few
weeks (doing builds of Python and Zopes, and running their test suites).
This gave me an opportunity <wink> to observe an oddity I thought I saw
before, but wasn't sure about:  when a lot of messages are coming in real
fast (all my accounts are POP3, at least cable-modem speed, and this is the
IMO version of Outlook 2000 -- no Exchange involved), and the machine is
struggling, seemingly random contiguous ranges of the fresh msgs don't get
scored.  It's like 10 get scored, the next 20 don't, the next 15 do, and so
on.  Outlook's Inbox display also updates in chunks when this happens.
There are no clues in the trace log that anything peculiar has happened:
there's no evidence there that we were ever told about the unscored msgs.

Note that I don't care.  The next time I start Outlook, the plugin finds the
unscored msgs and does right things with them.  It's just evidence that we
have no idea how Outlook decides whether to tell us about a msg, and
evidence that it won't tell us when (perhaps among other reasons) it's short
on spare cycles.

It's times like these I'm so glad Outlook is open source <wink>.
