Thanks for the links, they allowed me to find the following program,
yet again from Juliusz.

  http://www.pps.jussieu.fr/~jch/software/files/analyse-x.pl


It will parse the /proc/<pid>/maps of your X server for you and
present it in a very useful (and hilarious) way. I won't detail
it there, just run it and enjoy :-)

PS: and if you read the source code itself, you'll spot this
    comment at the start:

# Warning: this code is written in Perl.  By proceeding further you
# certify that you are a consenting adult and that it is legal in your
# locality to view Perl code.
