 I haven't seen problems with processes, but the subdirectories of
 `DOT_SAGE/temp/` have been polluted with many directories dating back to
 5.8 at least, because sage-cleaner was looking in the wrong directory.

 > Hmmm, ''in principle^TM^'' the Sage cleaner (with the patches from here)
 should have killed the ECL processes, but Andrey reported it did not, so
 (regardless of #12426) something seems to be still broken.

 In your testing, could you tell whether the correct PID (for the runaway
 process) was written to the correct file? How did the runaway process
 escape the cleaner?
