Of course, my continuing (but minor) beef with Darwin's paging mechanism is that there's no support for a proper UNIX swap partition -- I'd like to avoid the overhead of paging into a (potentially fragmented) filesystem file completely.

Most pagefile accesses are random and read or write very small blocks (16KB on Darwin AFAIK). File fragmentation hurts mainly when accesses to the file are long and sequential. If accesses are short and random, it makes little to no difference if the file is fragmented, especially the smaller the access is.
