[undertow-dev] The reason for removing reference to exchange object in HttpResponseConduit

As part of the below commit, i see that the reference to exchange object is removed after a call to processWrite which will generate the headers. https://github.com/undertow-io/undertow/commit/d0151d67a88bc34f61895bc6d1... When this is done, there could be still data which has to be written. Can you please help me understand why this reference to exchange is being made explicitly made to null? -- Regards, Rohan Emmanuel
