The update to FileChannelImpl looks right.

The change impacts the read methods of input streams obtained from Files.newInputStream and the write methods of output streams obtained from Files.newOutputStream. I'm wonder if we should create a new complete test for this long standing issue. Right now, the test only exercises the available method and I worry that it continues when it runs out of file desciptors.

I'm wonder if we should create a new complete test for this long standing issue.

The test needs some work anyway so I will investigate.

The test as of commit 899f28c passed 100 repeats on Linux and Windows with the change to FileChannelImpl, but failed all 100 repeats on the same platforms without the implementation change.
