D2720: debugcommands: introduce actions to perform deterministic reads

[indygreg (Gregory Szorc)]

indygreg added a comment.


  My only explanation is this is stdout output buffering and things are really hanging on the next read operation.
  
  Maybe try sprinkling some `ui.fout.flush()` and/or `util.stdout.flush()` and/or `sys.stdout.flush()` calls throughout the debug command? Maybe at the first thing in the loop that evaluates commands to execute?
