Why "must" it fail?

What is it about the IDLE terminal that prevents it from emulating an 
actual terminal, like all(?) the other terminal emulation programs 
people use?

I just opened my Konqueror file & web browser, gave the command "Show 
Terminal Emulator", and ran Python:

py> import shutil
py> shutil.get_terminal_size()
os.terminal_size(columns=85, lines=10)

That's spot on perfectly correct. I then resized the window and tried it 

py> shutil.get_terminal_size()
os.terminal_size(columns=108, lines=13)

I then quit Python, and ran idle3.3 from the Konqueror terminal. 
Unfortunately, get_terminal_size() returned the size of the *Konqueror* 
terminal, instead of the IDLE terminal. I think that's a bug. I don't 
know if its a bug in IDLE or get_terminal_size() or both.
