You can wrap in a Process struct or class and take advantage of 
the destructor to do that. Assuming you write standard GC-ed code 
the destructor should be called at the end or if you free 
manually the resources.

example API:

struct SpawnedProcess
{
private:
     Pid pid;
public:
     this();
     void execute();
     void terminate();
     bool running();
     ~this(){ if (running) terminate();}
}

P.S: i just see that in my own Process class i forgot to do that.
