          Issue Type: Improvement
          Components: beam-model

Hi. When using a python debugger, it would be nice to be able to debug ops as 
they are run locally by --runner DirectRunner however it seems that Beam forks 
the process to actually run the ops. Unfortuatnely most python debuggers (mine 
is pydevd) don't support following forks. It it possible to add a flag to 
DirectRunner to keep the DIrectRunner in-process?
