tev does not exit when the window is closed #216
Description
I have just been looking for an OpenEXR viewer, tried out tev on NixOS and started it from the shell with a Multilayer EXR image as argument, but when I close the window, the program just stays running until I kill it:
$ tev ./0047.exr
11:12:50 SUCCESS Initialized IPC, listening on 127.0.0.1:14158
