Neither the `time` executable from the GNU time package work completely
correctly, nor does the GNU Bash built-in one.

GNU time's *elapsed* value is off by some factor.
$ \time factor 1111111111111111111
1111111111111111111: 1111111111111111111

As above; also here all the running time should be attriuted to *user* time.
This is probably a [[!taglink open_issue_gnumach]].
