perpetual: new module for mapping file into memory

[Sergei Degtiarev via Digitalmars-d-announce]

I suggests a new module for mapping  files into memory. Instead 
of viewing the file as array of bytes, it directly maps the 
object onto file allowing to handle it as regular in-memory 
object. The data remain persistent after the program exits and 
may be re-opened and used again or shared between processes.
Dynamic arrays are also supported with some limitations.
The code is at

Is anybody interested?
