The real solution, in spite of the dozen alternatives we've
now produced, seems to be to use the win32pdh library
to access the "System"-> "System Up Time" value.  It
claims to return an 8-byte value, which likely doesn't
wrap quite so soon.  (And yes, remarkably, with the advent
of Windows XP Pro it is now possible to keep a Windows
machine running for longer than 49 days, even if it's
used as a development machine.  Well, for Python development,
anyway. ;-)

For the life of me, however, I can't figure out how to do it.
