1. the dll is loaded only once by the process, this is a Windows feature.
2. Your ECE entry point may be called multiple times in different contexts.
Nothing however prevents you from creating you ECE object only once and
storting a pointer to it in a global variable so you can rerurn it on
subsequent cals to yoru ECE entry point rather than returning a brand new
object.
