title: Write Only Memory Mapping in boost?
body: <p>Why doesn't boost interprocess support write only memory mapping?</p>
  
  <p>Maybe I'm missing something but wouldn't a write only mapping be significantly faster than a read/write mapping as the OS doesn't have to read in the pages from the disk, just flush out pages from memory to the disk? Also it would have the benefit of being entirely non blocking (except for flushing and destruction).</p>
  
  <p>Would I benefit by switching from boost to native OS memory mapping?</p>
