hmm - I compiled
https://github.com/TragicWarrior/libvterm
using Ubuntu 18.04 and don't see a problem (xfce4-terminal 0.8.7.3).
The vshell program works, and top shows a low load factor.
fwiw, most of the ncurses-related bugs reported in Ubuntu are mismanagement
by Ubuntu packagers... I'd suggest reporting it there, but couldn't expect
them to do anything useful.
