You can also use something like "auditctl -w /foo/bar -k myfoobarwatch
-p wa" to add a write/append watch to a file and then use ausearch to
mine the logs. 

Unfortunately there is no file to watch in this case since the list only
lives in the xserver AFAIK. I am afraid you'll have to use something
like xmon (xconns/mxconns might be enough though) to monitor what is
going on.
