basically a global variable is reported that kept track of the last 
found looseness

it's more that it only got set when there is a check for looseness which 
is not always happening (as it depends on other parameters as well) so 
then you get the old value (so that state is/was preserved)

i now always reset it

well, the internal code is also a bit ugly in passing around info (and 
by now i've gotten accustomed to extra housekeeping at the lua end)
