| There's currently a deadlock in StreamReader.readexactly() -- if the requested size is larger than the buffer limit for pause, the transport may be paused with no way to unpause it. See http://code.google.com/p/tulip/issues/detail?id=99 in the Tulip tracker. | ||

| I'd appreciate help writing a test. (Debugging this already set me back enough hours.) | ||

| I don't see anyone motivated to write a complex unit test for the issue which is already fixed, so I close the issue. Thanks for the fix Guido. |
