Expected Behavior

Xonsh should allow inputting a command while another command is running and not freeze afterwards

Current Behavior

While a command is running, if you enter another command, xonsh will freeze when entering a subsequent command.

Steps to Reproduce

$ sleep 5
echo hi # <- entered while sleep was running
$ echo hi
hi
$ clear
# freezes here

Hi! I can't reproduce this in xonsh --no-rc (xonsh/0.9.25.dev3) on Ubuntu 20.04.

Interesting, it repros with xonsh --no-rc for me on Ubuntu 20.04. I'm using xonsh 0.9.24 though, will try again with the latest version.

[aneeshdurg]

Yup, looks like this is fixed in master.

[aneeshdurg]

Actually it seems like it's only fixed when I run it in docker. Installing it to my system causes the issue to repro. For more info, I'm using urxvt as the terminal.

[anki-code]

This looks like need more debugging for reported terminal.

I'm going to close this because I can't reproduce this on the current main branch.
