I hope so:
a) It's generic enough that there's interest in using it in
a range of projects - there's nothing QEMU specific in it.
b) It's worked very well on the QEMU code that I wrote that uses it
for postcopy, and has been solid doing that for many months now.
c) I'm not aware of any suggestions for a different, generic solution
to solve the same set of problems.
d) It's got a good self test, that's survived heavy testing.
e) I think Andrea has addressed all previous comments on it.
