  - Enable pattern initialization in test builds
    
    Clang recently added a new flag which will initialize variables with an
    intentionally invalid (or likely to be invalid) pattern to catch
    accidental assumptions about the initial contents of a variable.
    
    This change enables that flag in test builds, and when combined with
    UBSan should help detect these conditions should they arise.

  - Initialize return code to 0
    
    If there is a handle in the wait list, but there is not an event,
    _hlist_do_poll_locked will return an uninitialized ret variable.
    
    This patch sets the default return code to 0, for no event.
