[sldev] Scroll back buffer causes rendering pauses.

[Ardy Lay]

I seem to be experiencing momentary rendering pauses when a line of chat 
is displayed.  The pause is showing up in fast timers as UI.  I notice 
the delay without fast timers displayed after a full day in world.  I am 
wondering if anybody else sees this and if so has it been investigated?  
Perhaps my 12+ hour Second Life sessions are a corner case and this 
pause isn't necessarily a problem.  A quick re-log and all is well again.
