We need three backends, something like the following:
- anonymous mmap (-object memory-ram,size=128M)
- file mmap (-object memory-file,shared=on/off,size=128M,file=FILENAME),
creates file if size property provided.
- mkstemp + file mmap (-object memory-hugepage,size=128M,path=PATH)
I don't think shared=on/off is useful in the third case, but it would be
trivial to add.
