These are failures on tests of asynchronous replication. With async the 
test client doesn't know how long it will take for a session to 
replicate, so it sleeps 300ms before switching from one server to the 
other.  There are hundreds of these switches made in the course of a 
testsuite run. If there's some hiccup during a replication (e.g. a bit 
longer than normal gc run delays it), the test client can switch before 
the replicated state arrives and you get a transient failure.

I bumped the sleep time a bit (and made it configurable via a system 
property.)
