Instead of creating your own new thread, it would probably be better to leave it up to the threadpool to run the save. It doesn't force it to run instantly like creating your own thread, but it does allow you to save threading resources.

The way to do that is:

ThreadPool.QueueUserWorkItem(Save);

The problem with using this approach, as well, is that you're required to have your "Save()" method take in an object that will act as a state. I was having a similar problem to yours and decided to go this route because the place that I'm working is very Resource-Needy.
