The strange 600 dpi behavior on peeves was due to /tmp filling up. The clist
file size is HUGE. It fills up the (limited space SSD) drive on peeves and
then we get strange results :-(

Good thing we have 64-bit clist file support. The final clist size is 273 Gb!

It hasn't finished yet, but the Outputpage start time was 11481 seconds. For
300dpi this time was 4364 seconds and 150dpi was 2040 seconds.

Interestingly, some of the performance hit may not just be the pattern clist
playback during the clist writing, but the rendering time. The 72 dpi page
rendered in 1 seconds, the 150dpi page took 4 seconds, but the 300dpi took 1860
seconds. As mentioned above, the 600 dpi case isn't finished yet. Even if the
600dpi rendering time won't be accurate since there was at least one cluster
regression while it was still running.
