Julian Hyde commented on CALCITE-1894:
--------------------------------------
The {{lines}} parameter, which is assigned to the {{skipLines}} field, is
intended to be the mechanism by which header lines (if any) are skipped. But it
is not used.
I'm not sure whether the {{Thread.sleep}} is also a problem. It probably is. A
delay is fine, but it should loop until it has read and discarded at least
{{skipLines}} of data, and only then start emitting results.
I think {{contentQueue}} is probably still the right approach. It is a
{{ArrayDeque}} but is used from a single thread so is safe.
