Note that the size of 'data' is arbitrary. To do this "correctly", you
should collect new data until a nil 'data' is passed or you reach other
criterion to stop collecting. For example:
coroutine.wrap(function(s)
local cs=""
while s do
cs=cs..s
s=coroutine.yield()
end
-- now work on cs
end)
Of course, it may be good to put limits on the size of 'cs', as the
routines in querylib have.
