With the help of generics I have been able to further
reduce string processing load.  Instances will adapt String
to fragments, as needed.
The result is another 20% speed-up.  A pleasant surprise,
and fairly easy.  This allows using simple renames for
key data. :-)

I'd like to further merge the programs, following the
comments so far.  In particular, there doesn't seem to be
a real loss when using tasks on a single core machine,
IIUC.  I'll try to confirm this some more.
We could then submit just one program, if you agree.
