You can use pipeShell and a control loop to check when the
ProcessPipes it returns is done.
example:
```d
void main()
{
import std.stdio, std.process, std.conv, std.random,
core.thread,
std.algorithm, std.range;
ProcessPipes[4] pp;
iota(0,4).each!(a => pp[a] = pipeShell("sleep " ~
uniform(1,20).to!string));
while (pp[].any!(a => !tryWait(a.pid).terminated))
Thread.sleep(dur!"msecs"(50));
writeln("done");
}
```
You can wrap in a struct to hide the ugly bits.
