see http://plan9.bell-labs.com/~rsc/thread/ and
read the introduction to alef by bob flandrena
linked there.

in terms of trite academic examples,

int x;
void inc(void*) { x=3Dx+1; }
void
main(void)
{
    int i;
    for(i=3D0; i<10; i++)=20
        threadcreate(inc, nil, STACK);
    while(x < 10)
        yield();
    print("everyone finished\n");
}

is correct (though tortuous) code.
using proccreate would introduce
the usual race.
