* The postream class represents an input communication channel with the
* child process. The child process reads data from this stream and the
* parent process can write to it through the postream object. In other
* words, from the child's point of view, the communication channel is an
* input one, but from the parent's point of view it is an output one;
* hence the confusing postream name.
*
* postream objects cannot be copied because they buffer data that flows
* through the communication channel.
*
* A postream object behaves as a std::ostream stream in all senses.
* The class is only provided because it must provide a method to let
* the caller explicitly close the communication channel.
*
* \remark Blocking remarks: Functions that write data to this
* stream can block if the associated handle blocks during
* the write. As this class is used to communicate with child
* processes through anonymous pipes, the most typical blocking
* condition happens when the child is not processing the data
* in the pipe's system buffer. When this happens, the buffer
* eventually fills up and the system blocks until the reader
* consumes some data, leaving some new room.
