Okay, so to do something equivalent I would need to use 
std.process. My next question is how to pass the common data to 
the sub-processes. In the Python approach I guess this is 
automatically looked after by pickling serialization. Is there 
something similar in D? Alternatively, would the use of 
std.mmfile to temporarily store the common data be a reasonable 
approach?
