A Servlet Container is at liberty to create as many Servlets instances that it deem necessary to achive high performance when you implement SingleThreadModel - or might make one instance per request it serves. This might be it? This model sucks - you should NOT use it. View the Servlet as a singleton that's shared between many threads - it's not that difficult (at all) to code around the desire to use instance variables.
