NOW you're bringing me back to freshman year :)
I remember building a system from scratch and having no "less" or "more"
tool, and the only way I could find a build error before it scrolled by
was to turn on the "smooth scroll" button.

My use case:
1) run windows 7 in a VM
2) use rdesktop (ubuntu xenial, rdesktop Version 1.8.3) to connect to
the windows box's desktop (used to run visual studio, etc.)
3) launch mintty, maximize the window
4) run a build that spits out a lot of logging. This can be simulated
with "od /dev/urandom".
On my machine, it will lock up the desktop for a while, until I can
switch desktops, ssh into the windows box, and kill the offending process.
This is certainly multiple bugs, since X11 shouldn't lock up in any
case. However, I can play fullscreen video over rdesktop without an
issue, so I'm not sure why the console is so graphically intensive.

This is true. Unfortunately, none of them have made it into distros
yet. A local build of xfreerdp 2.0 will work fine, BUT that version
removes a few features I use [insert oblig XKCD here]. So *shrug*.
