Re: [jbosscache-dev] State transfer tests in head
This was actually from a series of IM and phone conversations I had
with Brian around RegionManagers and Marshalling/Eviction Regions.
In the 1.x codebase, marshalling regions would queue calls made to
regions marked as inactive, and then apply these calls when the
region was activated. Sort of a way to deal with calls that may come
in to a cache before the cache has completed transferring state and
fully joins the cluster. We felt that with FLUSH in place, we'd have
a better solution. If this otherwise edge case starts becoming a
concern, enabling FLUSH would be the correct solution.

Ok thanks Brian. I do not remember "replacing queueing with
FLUSH"
but I
was not focused on that back then. I'll look.
