[chuck-users] Getting the status of running shreds *into* chuck

Have you ever gotten this working? I've tried it and it seems there's a problem with the way chuck buffers its output. The status lines don't come out until the process ends. The only way I've been able to read the status line without stopping the VM is to run chuck inside of GNU screen and log its output (screen -L chuck --loop), and tail the log file, but I don't know how to configure screen to make it constantly log its output; it seems to only log periodically, so there's a delay until you see the status output. I've tried a few different things with appending to files or writing to FIFOs but the way the chuck command writes its output always seems to pose a stumbling block.
chuck version: 188.8.131.52-beta-1 (dracula)
exe target: mac os x : universal binary
