Thanks, Yes, I needed to empty out the pipeline so that the process
can go away.  I changed to command to:

$   feob 563,grp104/match=and | -
    (read sys$pipe line ; define/job/nolog search_result &line ; -
    copy sys$pipe nl: )  ! must throw away the rest of the lines

I am still puzzled by this however.  Searching around I found several
examples where the emptying out the pipe isn't addressed.  Is it just
because my data is long enough to get into rwmbx state?
