While it was rendering, Memory usage of ProMSRendererTool hit about 2GB and then was stable, hovering around 1.81GB. compressord hung in there at about 128MB for the whole time. After about 20 min I got the "Your system has run out of application memory" dialog box.

This email sent to site_archiver@lists.apple.com BTW - I tried again with a simple project with one long clip and a third-party filter that isn't one of mine, and got the same results. Despite ProMSRendererTool only showing between 1.5 and 1.9GB used in the Memory column, I can see Virtual Memory and Swap Used steadily rising, about 125MB/sec.
