I have just realised I do not understand some basic things about
unbuffered FileOutputStream.

I used them in two ways, wrapping in a BufferedOutputStream or
BufferedWriter, or writing an entire file in one i/o without
buffering.

If you write single bytes at a time, will you trigger physical I/O on
every byte, or is there some small buffer in there anyway?

I have experimented with flush during file write. The file size stays
at 0 until I close, at least to DIR. 

What I want is to log bytes that will be largely recoverable even if
the program terminates unexpectedly without closing. Flush does not do
it.  Close/reopen periodically seem at bit heavy handed. Is there
something I am missing?
