Short version: When systemd-logind login.conf KillUserProcesses=yes,

Same thing with Xfce, so it's not DE specific. (Unsuprising.)

I inflated the size of the test volume, and it seems pretty clear that
the scrub is not completing, as the kernel threads stop sooner when
logging out vs not logging out. So the status reporting an
interruption appears to be valid for the net operation, not merely the
user space tool being interrupted.

You have your terminals set to start the shell as a login shell I'm 
guessing.  That's probably why closing the terminal window is triggering 
systemd's process killing.  It will of course still trigger when you 
close the graphical session though.  Personally, this is yet another 
reason for me to not like systemd.  This setting breaks traditional UNIX 
userspace semantics.

Personally, I'm with Duncan on this one though, if resume works 
correctly, then it's not a bug, just a bad interaction between an 
administrative tool designed for a server and an init system designed 
for a desktop.
