Public bug reported:
Memory leaks in xorg-server while video chat is running in skype 4.
To reproduce:
1. Update to the current version of 10.04.4 (i386)
2. install skype
3. run video chat.
Xorg will use all possible virtual memory in the system and OOM will
kill skype.
This is degradation, possible introduced by one of the latest updates.
Same configuration, with same version of skype 4, was running stable till I
did scheduled update week ago.
I perform an update once in one-two months.
