Rockslide seems to hang in production upon image upload

[mbr]

After an image upload, the entire podman service seems to hang:

curl localhost

Restarting it seems to fix the issue

root@sgflt:~# systemctl restart rockslide
root@sgflt:~# curl -v localhost
*   Trying 127.0.0.1:80...
* Connected to localhost (127.0.0.1) port 80 (#0)
> GET / HTTP/1.1
> Host: localhost
> User-Agent: curl/7.88.1
> Accept: */*
> 
< HTTP/1.1 404 Not Found
< content-length: 0
< date: Tue, 26 Dec 2023 02:23:58 GMT
< 
* Connection #0 to host localhost left intact

Note: This only happens on single-threaded executors and is caused by blocking std::process::Command.
