[filed for reference sake]
I can imagine bug fixes and improvements meaning that iterating over
blocks can give different results one gdb release to the next.
I don't want our hands tied because we're afraid of breaking someone's
python script.  This is an area where I can easily imagine change.

I'm not saying this can't go in, to the contrary.
But IWBN to have it written down somewhere that we make no promises of
absolute consistency one release to the next.
