Eliot, Webapp does appear single threaded on win32. I'd go so far as to say it's unusable in a production environment on win32. I develop using it on my win 2k laptop and deploy on linux or Solaris. Webapp is forever hanging when I try to execute concurrent requests from the same browser on windows. It seams OK on Unix though.
I think you should consider using mod_jk or mod_jk2 on windows as they are currently actively developed. However, I don't know for sure as I wouldn't even _think_ about deploying a production system on windows anyway... Sorry to be the bearer of bad news...
