[orca-list] for anyone on the bleeding edge

[Mike Gorse <mgorse alum wpi edu>]

Hi all,

I just committed a change to at-spi2-core and at-spi2-atk that we've been 
considering making for a while (see 
https://bugzilla.gnome.org/show_bug.cgi?id=650090 for details).

There is some risk in making this change late in the 3.18 cycle. However, 
it reportedly fixes various performance issues with large lists and such, 
so it seemed worth making. However, testing would be appreciated. To test, 
either pull the latest at-spi2-core and at-spi2-atk from git or wait for 
the 3.17.90 release (I plan on rolling a release on Monday).

Thanks,
-Mike
