Review Comment:
@sunchao Can you please take a look [at
this](https://github.com/apache/spark/compare/master...mridulm:spark:45052-suggestion-for-sunchao)
?
It should fix the issue we are discussing - the test is for illustration
purpose only, please do clean it up :-)
Essentially it is a minor modification to your fix - the issue is that
`blockManager` referenced in task cleanup in finally is incorrect - as you had
fixed.
The only change I introduced is to not need this to be passed in at a Task
level - but simply grab it at task start time - and also added a test which
validates this is indeed the issue.
