[Updated] D12628: worker: fix `_blockingreader.read()` to really block

[mjacob (Manuel Jacob)]

This revision now requires changes to proceed.

mjacob requested changes to this revision.


  `self._wrapped` is not non-blocking, therefore `self._wrapped.readinto()` won’t ever return `None`, therefore this change only adds dead code.
  
  The name of the class `_blockingreader` is misleading.
