Comment 6 for bug 1814905

Here's a quick demonstration with Ubuntu 18.10 desktop, fresh install in a VirtualBox VM, up-to-date

with and without strace.
I've also attached a perf trace output. I've started /bin/sh as root like this:

perf trace -o /tmp/dash-perf-trace.txt /bin/sh

Pressed a couple of enters, did an echo, and then a "wall foo" from another terminal, as normal user.

I'm not saying it's dash's fault, I just didn't know where to open the ticket.

Please let me know if you need anything else.

Thanks!
