Nope.  Measurement error.  Turns out running Firefox in wine
and then OpenOffice in wine makes OpenOffice start up fast,
since wine's in the cache.  Gotta reboot between runs of
even different apps.

I measured this again tonight.  It's still roughly true;
tonight I got 35 seconds native, 30 with Wine
(leaving wineserver and the helper window running between runs).

I suspect the reason is the slow shared library
loading that Michael Meeks is working on fixing.
Once that's in (if he can convince Ulrich Drepper),
native OOo should load as fast as OOo under wine.
