How you stubbed out the file io seems fine for the lifetime of 2.2.x
and maybe 2.4.x, but in the long run, I believe we need to support
some kind of "VFS" layer, to make all IO pluggable. (open file,
directory listing, etc etc).
Just thinking aloud on a few other benefits from a pluggable vfs layer.
* A stackable performance statistics vfs module implementation that
does timings on filesystem io calls.
* A statcache stackable vfs modules that just stubs out the stat
method and caches stat calls for a configurable amount of time (say 10
seconds).
* An audit logging stackable vfs module that logs all io calls (mainly
for debugging).
In a addition to having a way to mount a vfs hook implementation for a
given path, perhaps also an interface to replace a vfs hook with a
delegating entry so that it can be stacked.
