I can reproduce the problem you mention here  ( when a node in a cluster
becomes unavailable in the network, background UpdateStore ajax requests
to get the statistics time out after a long delay and block all other
pending UpdateStore ) and the patch fixes indeed the problem.

What I am wondering is why do we treat the UpdateStore requests serially
in the first place ?
