Public bug reported:
While running mtr, hitting 'P' to pause, causes CPU use to ramp up.
Pressing 'space' to unpause, resumes normal function and CPU use. This
consumes one (1) core at 100%.
While running mtr, hitting 'H' to get the help menu also pauses the
current traceroute/ping process while displaying a Help menu. However,
this pause does not cause excess CPU use and normal function and CPU use
are resumed when leaving the Help screen.
