independent or parallel process

[drpepper]

I want the function below to run independently -- like a unix
background process, without delaying subsequent code in main.  I
tried the following using std.parallelism:

void main() {
   function_a(int a, int b) {
    ...
   }

   auto new_task = task!function_a(11, 12);
   new_task.executeInNewThread(1);

   // more code ...
}


I get errors: core.thread.ThreadException ... unable to set
thread priority ...
