For this one, I just commented out the style rule for the "busy" throbber in the
modern skin's navigator.css.

With that, here's what I saw:

----- base/modern -----
00008.391: ...main1
00008.125: ...main1
00008.000: ...main1
----- noThrob/modern -----

----- noThrob/modern -----
00008.000: ...main1

00008.078: ...main1
avg1=8.114667 avg2=8.052000 diff=0.062667 (0.772264%)

Savings is slight, between ~0 and 0.77%.  Combining overlays won't help this
one.  We could consider (if worth the savings), disabling the busy throbber till
after the first page appears (or thereabouts).

This might be a case where the savings actually comes *after* the first window
appears so reducing this wouldn't buy us much, in reality.  This may need
further analysis.
