Warning and long delay (approx. 2-3s) when exiting the VM

[comunidadio]

The warning prints after 2-3s delay:

➜  matchlocktesting matchlock run --image alpine:latest -it sh
Using cached image alpine:latest
/workspace # exit
Warning: cleanup errors: [machine close: close socket pair: close host-net: file already closed]

Same issue with non-interactive exit (delay happening after 8.8.4.4 prints):

➜  matchlocktesting matchlock run --image alpine:latest cat /etc/resolv.conf
Using cached image alpine:latest
nameserver 8.8.8.8
nameserver 8.8.4.4
Warning: cleanup errors: [machine close: close socket pair: close host-net: file already closed]

Tested on macOS 15.7.3.
