Summary     : General purpose buffer program
Description :
This is a program designed to speed up writing tapes on remote tape
drives. After startup it splits itself into two processes.  The first
process reads (and reblocks) from stdin into a shared memory buffer.
The second writes from the shared memory buffer to stdout.  Doing it this way
means that the writing side effectly sits in a tight write loop and
doesn't have to wait for input.  Similarly for the input side.  It is
this waiting that slows down other reblocking processes, like dd.
