Actually, I've determined that "xmllint /tmp/SVG.xsd" is sufficient to
trigger the problem.  I have the following limits set:

  lakeview ok % ulimit -a
  -t: cpu time (seconds)         unlimited
  -f: file size (blocks)         unlimited
  -d: data seg size (kbytes)     unlimited
  -s: stack size (kbytes)        unlimited
  -c: core file size (blocks)    0
  -m: resident set size (kbytes) 1048576
  -u: processes                  unlimited
  -n: file descriptors           1024
  -l: locked-in-memory size (kb) 64
  -v: address space (kb)         unlimited
  -x: file locks                 unlimited
  -i: pending signals            16382
  -q: bytes in POSIX msg queues  819200
  -e: max nice                   0
  -r: max rt priority            0

and I still have a problem.  I don't think the RSS value works with this
kernel, but even if it does, I don't think only 1 GiB is unreasonable
for RSS.

I can reproduce the problem consistently, so if there's something you'd
like me to do to test it, let me know.
