I've come up with two basic approaches, one uses the main 
thread as a relay, and the other uses a shared array of 
Tid...thus:

import    std.concurrency;
import    std.stdio;

import    core.thread;

shared    Tid[8]    tidList;

void    worker (int ndx)
{ Thread.sleep (5.msecs);
    writeln ("worker is done");
}

void    main()
{
    auto tid    =    spawn (&worker, 0);
    tidList[0]    =    cast(shared Tid)tid;
    Thread.sleep (40.msecs);
    writeln ("main is done");
}

Is there a reasonable way to decide which way is best?  Is 
there a better way that I just haven't thought of? Are there 
problems with sending messages via shared Tids that I just 
haven't thought of yet?

I'm sending immutable Tid[string] to each thread, though I don't 
spawn new threads after app initializing. Works well if you don't 
have to encapsulate your threads.
