[orca-list] have big speed difference with Orca preferences and Orca application-specific preferences dialog closing time

[Hammer Attila <hammera pickup hu>]

Hy,

I see big performance speed difference with Orca preferences dialog 
(Orca+Space) and Orca Application-specific preferences dialog closing speed.
For example if I launch Yelp application, simple opening the Orca 
application-specific preference dialog and closing the dialog with Esc 
key or clicking Ok button to save new preferences, I need waiting 10 
second before Orca is begin talking again.
When I using normal Orca preferences dialog command (Orca+Space 
keystroke), I need waiting only 3 second if I closing preferences dialog.
I see similar time difference values with Gedit, Firefox applications, I 
think this is not depending what application are launched.

Reproducation steps if you would like testing this problem or verify:
1. Launch any application, for example Firefox or Yelp.
2. Press Orca+Ctrl+Space keystroke.
3. Simple press Esc key to close the dialog, or click OK button.
You need wayting 10 second to Orca speech again.

I don't no braille showing this problem, I only using Orca with speech.
I reported this issue and attached a debug.out file with following
