            Bug ID: 144869
           Summary: [Streams API] ReadableStream reader should not be
                    disposable when having pending promises
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org

Currently, ReadableJSStream::Reader is disposed as soon as the JS scripts loose reference to it.
Once disposed, the stream is released, which forbids resolving promises when the stream is changing, like going to close state.
This happens even if the closed promise is actually set. 
The reader should be kept alive as long as there are pending promises to the reader and the stream can change of state.
