So far, I haven't had any success with the unit tests even though the 
normal usage works fine...

The thread's run function has something to the effect of:
while(1){
   char[] command = inStream.readLine();
   process(command);
}

It seems that readLine does not block with a memoryStream like it does 
with din and dout.  What's the best work around?


PS: I tried the following but had no luck.  process(command) never got 
called after the unit test wrote to the stream (with writefln):

while(1){
   char[] command = inStream.readLine();
   if (command.length == 0)
     continue;
   process(command);
}
