[orca-list] Corebird also stop working

[Francisco Javier Dorado Martínez <javier tiflolinux org>]

Hi all,

I am having same issue with Corebird twitter client, when tehre is a lot 
of tweets in the list and application gets focus, when Orca has a lot of 
events to process for any reason
stop working and you have to restart it to get working again.

The same behaviour with Eclipse and Thunderbird.
Now that we can disable Dead/defunct checking easier I will be testing 
in both situations.

Many thanks,
regards
Javier
