Hi Daniel,

I must admit I don't get this kind of safety.

There are no "potential problems with compression extending beyond the first 
fragment", there simply is no support for that right now.
So don't do it.

Whether you program your implementation so that it never even tries to or 
whether you use the space if it is sufficient is a quality of implementation 
issue.
