Thanks for the answer.
I checked.
Thread.getAll [x] .id is of type ulong, and spawn is of type Tid, 
moreover, they do not intersect in value either. But even if the 
program spawns a single thread, Thread.getAll [x] .isRunning 
returns true after the function terminates. Perhaps you need to 
wait some time.
You may have to send a message before exiting the function. Just 
look at the possibilities of std.parallelism.
I will gladly try other solutions. I would be grateful for your 
suggestions.
