Wes McKinney commented on PARQUET-474:
--------------------------------------
I figure right now we can leave it to the users to handle threadsafety
themselves in the course of implementing the RandomAccessSource interface. I
don't see a problem necessarily in putting a lock in the LocalFileSource class.
I'd frankly be in favor of eliminating Seek from the public API since "read
range [possibly buffered]" and "write to stream" are the only really necessary
operations.
