  I looked at this again, and you're right that most of the X server gets
swapped out:

6426 root     -10 -10 21588  16M 4336  1508 S <     0  5.7  9.1   0:56 XF86_SV

  However, it seems to be going into swap rather than being deallocated.  I
only get this if I run more than one instance of civclient at once, and then
it doesn't *seem* to go up unless I run even more.  My guess is that the X
server is sitting on allocated memory for future use.  So this isn't a
problem.
