There are no important advantages of IMultithreaded* to be had, and there are real costs of implementing this interface. It is clear that we should discourage implementation of channels as IMultithreaded*, and I think deprecating the interfaces is the clearest way to communicate this without ambiguity.

Proposal Implementation

• Fix Apply patch attached to UP-1362: Allow multiple threads to concurrently instantiate channels
• Mark all IMultithreaded* interfaces in uPortal 2.4.-patches, 2.5-patches and 2.6 as deprecated.
  • IMultithreadedCacheable
  • IMultithreadedChannel
  • IMultithreadedCharacterChannel
  • IMultithreadedDirectResponse
  • IMultithreadedMimeResponse
  • IMultithreadedPrivileged
