redefining controller makes duplicate clients #73

Open caseyjlaw opened 5 years ago

caseyjlaw commented 5 years ago

If a realfast_controller instance is redefined, then some commands suggest that there are multiple distributed clients going.

In [38]: rfc.restart()

This happens when event loop is not closed properly (with shutdown or close methods). Issue should have been fixed by https://github.com/dask/distributed/pull/1073, but that was a while ago.
