The last person I remember testing async marshalling extensively was Craig Bomba who was
indeed the one to spot the re-ordering.
I can't remember 100% cos we discussed this on IRC, but I think he used to see a nice
performance improvement with async marshalling, but I think the reordering made it not
usable for him.

Nope, the default value is not the one pointed out but rather the ones indicated in
https://docs.jboss.org/author/display/ISPN/Default+Values+For+Property+Ba...
Which comes from:

marshalling not to happen in caller's thread - that's for async replication
*only*) by passing the marshaller(an adapter) to jgroups which would then serialize it in
the (async) replication thread?
