Calling <library>Initialize Multiple Times - MATLAB Complier

The documentation isn't totally clear, what happens if I call <library>Initialize and <library>Terminate multiple times in a process? I've read some thing that says this leads to undefined behavior. I've been using this paradigm in my software and I've never noticed a problem. I just want to make sure I'm not getting lucky.

For that matter, I've never used the mclInitializeApplication() call either. There is a comment in the code I inherited that says the <library>Initialize() function will call the application initialization routine if necessary. Is this true? The documentation leads me to think it isn't, but again, the code works.
