Commit Message
On Ice Lake and Tiger Lake laptops, some test programs timeout when there
are 3 "make check -j8" runs in parallel. Add --with-timeoutfactor=NUM to
specify an integer to scale the timeout of test programs, which can be
overriden by TIMEOUTFACTOR environment variable.

Maybe add “This factor can be set at run time using @env{TIMEOUTFACTOR}
environment variable.”?
The mechanics of the patch look right to me.
Thanks,
Florian

I changed it to
@item --with-timeoutfactor=@var{NUM}
Specify an integer @var{NUM} to scale the timeout of test programs.
This factor can be changed at run time using @env{TIMEOUTFACTOR}
environment variable.
in the v2 patch.
