Bug: elastic.scroll does not return nil sid when there are no more results
The code in pminfo.lua assumes that elastic.scroll will return a nil sid
when there are no more results.
That is not the case - the sid will just remain the same.
When there are no more results the hits array will be empty.
The only reason the code does not loop forever is that there is a max loop
count of 5.
As well as being inefficient, it's possible that some results may be missed.
The code in stats.lua also assumes sid will eventually be nil.
However it also checks the hits array, so the sid check is merely redundant.
