Yes.
Strict session patch reject uninitialized session ID, thus it
prevents session adoption/fixation.

I know session ID collision will not happen most likely, but
there are few people who worries collision. We can check
session ID collision when it is generated.

It's easy patch, but I didn't include the patch to focus on
adoption.
