I would like to know if there's a way to batch a certain amount of writes done inside a job and display it sequentially on the main process.
My idea is to prevent the main process from freezing while displaying the batched data. The main process's device could be
the terminal or the Studio output.
%Studio.Debugger does something close to that when printing the output from the debug target process.
$System.Event.Signal($zparent) doesn't signals the parent if a device is open. So I can't create the batch buffer along, because I can keep the buffering device open and notify the main process.
I tried using an IJC device, but I couldn't get the buffered data back from the writer device using the reader device.
Also what does ChangePrincipal ($zu(132)) do?
