------------------------------+--------------------
'''Overview:'''
After using the control interpreter to send a command and returning to the
graph screen, 'qq' does not exit to shell. Nyx seems to get stuck and
never exits.
'''Steps to Reproduce:'''
Run nyx, cycle through to Control Interpreter, press [Enter] to start
interpreter, type SIGNAL RELOAD[Enter], Press [Enter] to quit, cycle back
to graph panel, type 'qq' to quit. Window disappears but hangs and never
exits back to shell.
'''Expected Results:'''
Program should exit and return to the original shell.
'''Actual Results:'''
Nyx disappears but does not return control to shell.
Pressing control-C from here yields:

'''Misc Info:'''
Nyx Version: nyx version 2.0.4 (released November 5, 2017)
OS: CentOS Linux release 7.4.1708 (Core)
Kernel: 4.4.96-mainline-rev1
Python version: Python 3.4.5 (default, Dec 11 2017, 14:22:24) [GCC 4.8.5

Nyx installed via npm.
I run nyx using: sudo -u tor nyx
Additionally, the direction by which you access the control interpreter
and subsequently the graph screen may matter.
If I go "left" from Screen 1 to Screen 5, use the interpreter, exit it,
then go left to screen 4 all the way to 1, qq seems to return to shell
normally.
If I go "left" from Screen 1 to Screen 5, use the interpreter, exit it,
then go right from screen 5 to 1, qq hangs with the symptoms described
above.
