The purpose of using $self is so that you can have more than one object, each with its own member data. The original code allowed people to create multiple objects, but each accessed the same hash. I don't see any real reason to use objects in that case.

My $self doesn't access %serverMap. Each object gets its own copy of that data.

I changed my constructor to throw out unnecessary code and to allow inheritance by using the two-argument form of bless, which is almost always the right thing to do.

My code doesn't create a singleton, but I wasn't sure if you needed that.
