I tried this first, but `IOUtil.configureBlocking(fd, blocking)` needs a `FileDescriptor` object instead of an `int`:
`public static native void configureBlocking(FileDescriptor fd, boolean blocking)`
And I did not find any public FileDescriptor constructor taking an `int`.
I would be happy for any hint to avoid this double implementation of configureBlocking
