In #48962 a member X has replicated region and is updating it. Members A and B are started up
in parallel. At the same time X decides to close the region. Member A manages to tell X that
it's creating the region and receives an update that B does not see. B finishes GII with no
content and then A gets its initial image from B, leaving an inconsistency between them.
<p>
The test installs a GII hook in A that causes it to pause after announcing creation of the
region.
<p>
X then creates its region and does an operation and closes its cache.
<p>
B then starts and creates its region, not doing a GII from A since A is still initializing.
<p>
A is then allowed to start its GII and pulls an image from B.
