however this triggers a thought (ouch !)

usually, a "dumb" program is not optimised by the programmer
who leaves the compiler do the whole work.
Introducing parallelism, even inside a sequential program, can
maybe help the programmer partition the software in such
a way that the software can better optimise the code.
This can help for example for loop merging and stuff like that ?
