kgtk --progress cat Does Not Report Progress when Using a System Copy

kgtk --progress cat does not report progress when using a system copy.

bg=True should have been _bg=True to run the system command in the background.

The architecture for monitoring is wrong. The problem is that the subshell does not read the input file, aone or more cat/gunzip/etc. commands under the subshell are doing the input.

Apparently pv changes are causing problems.

[CraigMiloRogers]

pv was changed to not produce output when connected to a terminal but not on the foreground process group for that terminal.

[CraigMiloRogers]

Three options:

• Find a way to set pv's process group to the top process group
• Pipe pv's output through cat
• Implement a pv substitute in Python

Could not read the progress terminal's process group.

progress_startup: exception getting process monitoring tty control group for '/dev/pts/2': [Errno 25] Inappropriate ioctl for device

[CraigMiloRogers]

Piping pv's output through cat didn't work, either. Perhaps there's a problem in my current version of Linux?
