After some number of operations that write to/clear the echo area, I sometimes see an exception logged:

NSMutableRLEArray objectAtIndex:effectiveRange:: Out of bounds

This seems to occur when #/attributesAtIndex:effectiveRange: is called on the textstorage object associated with an echo-area buffer; the hemlock buffer seems to be non-empty, but the parallel mutable attributed string has length 0.

I'm not sure what (hemlock stream operations ?) causes them to get out of sync.

Sometimes this seems to be recoverable; other times, it doesn't.

The ApplicationServices framework includes important image processing classes needed for mapping files to OpenGL textures. Likewise, QuartzCore and Foundation have useful routines for other graphical applications.

I'm attaching the populate.sh files I used to generate the CDB files for my use.

It looks like we could save a byte of space by using a shorter encoding of MOV in the following cases.

Images built with this change applied seem to work fine. The images are abut 28K smaller---a savings of about 0.2%, if it's even meaningful to make such comparisons.
