Are there any scenarios of which you're aware that would cause
this query to loop endlessly? I just tried this on another program,
and let the query run for a good 10 minutes before I killed it.
The job had no halts; the CPU was running, and the temp storage on
the job was climbing into the tens of gigabytes. I'm not sure how I
would debug this. The other five programs I tried with this finished
within 5 seconds. I would expect the depth on this program to be no
more than 10 levels, probably closer to 5.

In the looping case, for which the CYCLE specifications apparently could not properly stop the iterative processing of recursion, what was the result set for the initialization SELECT; i.e. what was the result-set of the following query, replacing :iObject with the the program name specified as the value for which the looping was exhibited as the effect?: 

     select WHFNAM, WHOTYP, WHLNAM, WHPNAM
       from PGMREFS
      where WHFNAM = :iObject
        and WHLNAM not in('QSYS', 'QGPL')
And what was the Display Program References (DSPPGMREF) that generated the data for the Output File (OUTFILE) named PGMREFS that was referenced in the above SELECT?
Just a SWAG, but if the following predicate was appended, ANDed as composed, to the above query, does the problematic looping persist or is the issue resolved?: 
        and WHFNAM <> WHPNAM
