Oct 11 incident

The Oct 11 incident was mostly Firefox opening a large number of PDF documents
with massive use of (rather low-res) graphics. Probably kept a number of them
buffered somewhere? I'll quote the first and the last TWO lines, since the
penultimate one seems similar to the last one of the previous crashes.
