Deliberate non-handling — the Task spelling of promise.catch(Failure.ignore(reason)). Swallows every rejection (bugs included: this is for cleanup whose failure genuinely has no consequence) and says so on stderr under QUNITX_DEBUG instead of vanishing.

Unlike every other method this one starts the task: "the outcome does not matter" is not a decision laziness can defer, and eager attachment is what keeps a fire-and-forget call site from ever holding an unobserved rejection.

import { unlink } from 'node:fs/promises';

Task(unlink('/tmp/qunitx-daemon.sock')).ignore('daemon socket unlink'); // fire and forget
await Task(unlink('/tmp/qunitx.lock')).ignore('daemon lock unlink'); // or join the cleanup
