b519509349 core/io: Add internal in-memory MemoryIO to all IO layers 
Honestly I don't have 100% sure if this is a good idea, the reasoning is that in any IO we'll want to do memory only operations like creating tables etc, so may want a common way to access it

0638550be7 Merge 'Remove unnecessary reference counting from completion I/O callbacks' from Preston Thorpe 
I am on a bit of a mission to revisit a lot of the ref counting, this
was an easy first win.
It seems to be a linear path of function calls or hashmaps which can own
the completions directly, no cloning needed.
