Hi guys,
Russell is correct. In CI we gather the responses as they come in, in
whichever order they're received. We make some effort to flatten the
result, but we take the approach of being "smart enough to get you the
results, but no smarter".
We don't do anything to reorder or manage the results in the way that the
HTTP interface does as we feel that's behaviour that the user of the
library should decide to implement should they desire it.
HTH.
