Question:
Can we mmap() files/ports into the memory map of a process. The
reason I'm asking is that I've been thinking about an Object Oriented
File System (basically just a persistant object store), and mmaping
seems to be one of the easiest ways to achieve it.
Not really. Read "Transaction Processing" by Gray and Reuter.
The problem with a mapped file interface to a persistent store
is that there is no obvious way to control when pages get fetched
from and flushed to disk.
