Re: [orca-list] Orca being restless

[Mike Gorse <mgorse alum wpi edu>]

Hi Jon,

Thanks for the suggestion.  I ran orca in a profiler, and you were right; 
there is a function in pyatspi called releaseGIL() that adds an idle 
handler which sleeps for a short amount of time and then runs again. 
Apparently it is intended to allow other threads to run.  It is very old 
code, so I'm surprised that I haven't noticed trouble with it before and 
wonder if there is something else at work, but that function is certainly 
involved.
