  52. As discussed on IRC, this leaves us with a race condition between  
    53. 

  53. close() and queued messages. The spec says that once close() is  
    54. 

  54. invoked, incoming data should be dropped, but queued tasks to dispatch  
    55. 

  55. message event will still be coming.
    56. 

  56. 

  57. This race condition can of course be fixed without much difficulty. It  
    58. 

  58. may be more difficult to similarly rearrange XHR specs.
    59.

  60. I find it unfortunate that where the spec says &quot;queue a task&quot;, most  
    61. 

  61. (or all) implementations will perform those actions immediately. This  
    62. 

  62. may be indistinguishable from JavaScript client code, but it will be a  
    63. 

  63. source of confusion for developers.
