a modulus comparison may be implemented within the ~while read~ loop
so that a correction is made after some fraction of the expected lines
to be read are read.
+** TODO Account for "early-exit" bug in input script
+2020-07-14T03:00Z; bktei> What happens if the script piping its stdout
+into ~bklog~ immediately exits without providing any stdout (ex: a
+python script with a missing module)? ~bklog~ should be able to detect
+the latest exit code and exit early. It should also be able to detect
+if the incoming pipe is closed.
