VS Code CodeLLDB debugger does not restart cleanly

If you launch this process with the VS Code debugger using CodeLLDB, when you restart, it fails, because the server does not close before the Meson build task starts (Meson can't write to the file because the executable is still running.).

I'm not sure how to fix this, but it would be nice to have. (I hoped #127 would have fixed the issue, but that seems to be a separate problem.)
