This sounds completely wrong. Do you guys remember the Subject: string
of this discussion by any chance?
It's very likely that tools do indeed loop when they see EAGAIN, but
this is a workaround, not the main mode of operation. It seems obvious
to me that the get method should wait until the scan results are
available. Perhaps the discussion had a specific scenario where
EAGAIN would make sense, but I cannot imagine what it might be.
