Streams serialized with the default nsIInputStream serializer will be serialized with delayedStart, meaning that when sent from the parent process to the content process it will be serialized as a RemoteLazyInputStream. In the specific case of SendOpenStream this causes issues, as the content process code depends on the synchronous nature of nsIFileInputStream to allow it to be wrapped in a SnappyUncompressInputStream, which requires a sync stream. Relying on this property is not generally correct and only works because we know only nsFileInputStream will be sent by the parent process. Other types of sync streams may be received as async if they are sufficiently large, such as nsStringInputStream. Differential Revision: https://phabricator.services.mozilla.com/D103227
