Yeah prior to background job support, pausing the foreground process with CTRL-Z was a major footgun—nushell didn't detect when the foreground process was paused, nor did it offer any way to unpause it. The terminal was rendered useless until you manually resumed/killed the paused process via another terminal or GUI. Nowadays `job unfreeze` will do the trick.
