Missing initial value of memory tags #26

The specification does not clearly state what the memory tag of a memory chunk is, that has not been tagged by SETTAG or SETINVTAG.

We touched on this in the last call, and Florian mentioned that a tag is always defined by assuming the kernel would back the tag storage with zero-pages. However, unless it is specified that uninitialized memory tags are zero, a random number would be specification-conform as well.
