Pretty small fruit.  Based on my measurements
(http://lists.laptop.org/pipermail/sugar/2008-March/004669.html), we are
talking about less than 200 ms for typical Activities.  The only
Activities I know of with enough code for this to matter are the TamTam
activities.  Even the Journal spends much less than one second compiling.
~ Additionally, my measurements include the time to write the pyc file back
into jffs2, so the real launch delay could be even less.
