Public bug reported:

Binary package hint: compiz

I noticed today that compiz had hit 4G of memory over 2 days. I updated
to the latest of everything today and rebooted, after following a
modified version of https://wiki.ubuntu.com/X/DebuggingWithValgrind and
https://wiki.ubuntu.com/Valgrind against /usr/bin/compiz, and am
attaching the valgrind logs now. Summary shows:

==7291== LEAK SUMMARY:
==7291==    definitely lost: 148,549 bytes in 1,898 blocks
==7291==    indirectly lost: 2,488,656 bytes in 14,344 blocks
==7291==      possibly lost: 1,527,217 bytes in 4,375 blocks
==7291==    still reachable: 28,831,515 bytes in 63,181 blocks
==7291==         suppressed: 0 bytes in 0 blocks
==7291== Reachable blocks (those to which a pointer was found) are not shown.
==7291== To see them, rerun with: --leak-check=full --show-reachable=yes

With the most extreme:

==7291== 404,504 (4,320 direct, 400,184 indirect) bytes in 54 blocks are definitely lost in loss record 24,631 of 24,640

$ bzcat /tmp/compiz-valgrind.log.bz2 | grep '== [^ ]' | grep 'definitely lost' | wc -l

This is from running compiz (with Unity) for about 5 minutes.
