I finally fixed the problem. It's a little embarassing, but maybe the solution will help someone else...
I had been editing files directly in the my webapps/ROOT directory instead of redploying from the WAR file each time. I decided I should update the WAR file so I could deploy from it. But I was worried the new app wouldn't work right, so first I renamed webapps/ROOT to webapps/ROOT.bak2 (so I could go back quickly if it the WAR deployment didn't work). It turns out that apps in that directory (webapps/ROOT.bak2) was still being deployed and still handling requests that were also being handled by webapps/ROOT. Oops. I'm not sure why it was being delayed by a minute, or why it didn't just blow up entirely.
