+ *
+ * proper-lockfile depends on graceful-fs, which monkey-patches every fs
+ * method on first require (~8ms). Static imports of proper-lockfile pull this
+ * cost into the startup path even when no locking happens (e.g. `--help`).
+ *
+ * Import this module instead of `proper-lockfile` directly. The underlying
+ * package is only loaded the first time a lock function is actually called.
