67** To reduce the overhead of returning from C functions, the presence of
68** to-be-closed variables in these functions is coded in the CallInfo's
69** field 'nresults', in a way that functions with no to-be-closed variables
70** with zero, one, or "all" wanted results have no overhead. Functions
71** with other number of wanted results, as well as functions with
72** variables to be closed, have an extra check.
