-/**
- * A helper to clear out the existing downloads known to the mozDownloadManager
- * / downloads.js.
- *
- * It exists because previously mozDownloadManager.clearAllDone() thought that
- * when it returned that all the completed downloads would be cleared out.  It
- * was wrong and this led to various intermittent test failurse.  In discussion
- * on https://bugzil.la/979446#c13 and onwards, it was decided that
- * clearAllDone() was in the wrong and that the jsdownloads API it depends on
- * was not going to change to make it be in the right.
- *
- * The existing uses of clearAllDone() in tests seemed to be about:
- * - Exploding if there was somehow still a download in progress
- * - Clearing out the download list at the start of a test so that calls to
- *   getDownloads() wouldn't have to worry about existing downloads, etc.
- *
- * From discussion, the right way to handle clearing is to wait for the expected
- * removal events to occur for the existing downloads.  So that's what we do.
- * We still generate a test failure if there are any in-progress downloads.
- *
- * @param {Boolean} [getDownloads=false]
- *   If true, invoke getDownloads after clearing the download list and return
- *   its value.
