There was another error I was seeing that went away, for no apparent reason. But it may help you reproduce the hang I was seeing.
I was seeing an XML validation error on the web.xml file. It showed the allowable DTD structure for the web-app element, but careful inspection of that file multiple times didn't turn up anything wrong with it. (It was the same file I had used successfully with 3.1) I reformated a bit for readability, and after saving the file, the error went away. Strange and mysterious for me, but it may be another way to reproduce the install-hangs- and-crashes-Tomcat problem.
