Just to provide some rationale for the initiator/completer terminology,
the very first implementation we did of this used 'sender/recipient (or
something along those lines I think), and we ended up confusing
ourselves massively. The main issue is that memory doesn't necessarily
'flow' in the same direction as the transition. It's all fine for a
donation or a share, but reclaim and unshare become funny. 'The
recipient of an unshare' can be easily misunderstood, I think.

So yeah, we ended up with initiator/completer, which may not be the
prettiest terminology, but it was useful to disambiguate things at
least.

Thanks for the review!
Quentin
