> Brandon Inman recently reported an undesriable behavior in the CSV file source group of files. Currently, the CSVLineReader, if reading a malformed CSV file, can enter a state where it is perpetually waiting for an end-quote character. As he put it, "Malformed files are malformed files and should probably fail in some regard, but a hang is obviously undesirable." 
> Essentially, the CSVLineReader needs to be tweaked in such a way that an informative exception is thrown after some threshold is reached, instead of basically just hanging.
