Detached bash processes block Murex from closing

[tiymat]

Describe the bug:

1. From Murex, run bash
2. Spawn and disown a long-running process, e.g. sleep 20 & disown
3. Exit bash with exit
4. Attempt to exit Murex with exit

The exit command will block until the disowned process terminates.

Expected behaviour: If the long-running process is managed by Bash, shouldn't Murex be able to close while the process is still running?

Screenshots: N/A

Platform (please complete the following information):

• OS, output from uname -a if supported: 6.10.8-arch1-1
• Terminal Emulator: kitty 0.36.2
• Murex version, output from version --no-app-name: 6.2.4000

Additional context This is quite a specific edge case and likely not very important in the scheme of things but I thought I'd file an issue to document it anyways.
