Description

In a multithreaded setting, we may spawn many threads which will have access to a shared IO resources. It may be useful to create a thread-safe IO queue implementing the arrow::io::ReadableFileInterface, limiting the number of concurrent requests to the desired number (which may be 1, for services not permitting concurrent access).
