Hello!

First of all, thanks a lot for your help - I really appreciate it.

I applied your new patches on top of your old patches. Hopefully that
was okay.

Unfortunately, it didn't work this time. Here's a sample output from the
new patch.

The interesting thing is that even though there is a lot of free memory at the
end, it still hangs. I also included the timestamps; note the one and two second
delays between the passes.

Please let me know if there is anything I can do.
