Hi @shollander
The Java 17-EA builds which seems to be fixed in the latest EA; may you
please rebase on master, all builds are green there.
This appears to introduce some duplication with
`org.apache.commons.io.input.BufferedFileChannelInputStream`; it would be
better if this cleaning functionality was defined only once and reused.

> A very useful tool for improving performance with disk-based IO is the use of
> memory mapped files. I propose an {{InputStream}} that provides a bridge
> between memory mapped files and the {{InputStream}} ecosystem.
> In my limited performance tests, the use of the MemoryMappedInputStream
> provided a 25% increase in throughput.
