Reading your suggestions and also packages provided by other posters I am
getting really unsure which way to go...

My main focus is making it as portable as possible, yet as simple as
possible.

My program will 90% percent of the time wait for the spawned program to end
before printing its output, but will on some occations read information
from the program's pipe while it is still running....

Any clues on which solution to choose ?
