I'm trying to use the client/server feature in fio 2.0.10
vanilla and I'm finding that "All clients" prints too soon.

For a while it was totting things up after four clients,
which kind of made sense... now it's stuck on three. Back when
it made more sense I thought that maybe handle_ts only dealt with
the information from a single thread for each client rather than
the aggregate of multiple thread jobs. That part seems to hold
true even when it doesn't have the info for all the clients.
Is this reporting the aggregate as expected?
Is there a parameter change that I need to make to get
the output I expect?
