title: boost::interprocess::managed_shared_memory: Grow(): Memory Reused?
body: <p>I am using boost::interprocess::managed_shared_memory. Initially I allocate say X mb memory. When process ran out of memory, we grow the memory by a fixed value (say Y mb, perform unmap-> grow()-> map)</p>
  
  <p>While growing, if contiguous memory is not available then a new chunk with X+Y mb is allocated with a different base address. What happens to previously allocated X mb chunk? Does boost take care of deleting it since it is already unmapped and no process is referring to it?</p>
