Those two are currently loading an object in thread 2. Thread 1 tries to
load an object as well, however, ClientStorage only allows to perform
one load on each client at a time, so the second thread is sitting there
waiting for the load of the first thread to finish.

This one looks healthy. One thread is loading from the ZEO server, the
other doesn't have anything to do.

Can you figure out whether those loads ever finish? Do you see any
network traffic on the ZEO port from the server (i.e. is data
transferred)?
