Is there currently - or has there ever been - any serious or significant problem with PHP's built-in session handling?

I mean, it's always worked for me and my projects.

But I see some codebases and frameworks out there seem to use a custom handler. Is this reinventing the wheel? Or improving on some flaws? What flaws?
