Just thinking out loud: should the write() return before the
underlying OS written everything or wait until the the system has
finished sending all the data? What is the philosophy that is
used in the java.io classes with regards to this? Maintaining a
certain consistency with the approach used in java.io would avoid
unexpected surprises for developers used to a certain behaviour.
