I have an ext3 directory with close to 10^6 files in it, and it has
no problem reading a single file.  The app is pretty slow adding
"the first" file, but after all the relevant data structures are
cached, adding more files is a snap.

The size of the average email in D-User (2006q3) is 5150.46 bytes,
just a smidge over 5KiB.

So an mbox with 2*10^6 d-User emails in it would be (decimal)
10.3GB.  Do most mbox support libraries have long-file support?
Even if they did, deleting an email from such a file would be
painful in the extreme.

As for Maildir, ext3 could handle that.  Reiserfs could, but don't
know what it would gain you, since it's forte' is *small* files, and
I think that 5KiB is just a bit too big.

Either way, it is the MUA that must analyze the headers and put them
in thread-order, and that would just be a beast.

Besides, how does one manage a 2*10^6 email folder?  My 21" monitor
running at 1280x1024 can only display 45 email subjects.  That would
be *44,445* screens of emails.  Totally unmanageable by humans.

Is "common sense" really valid?
For example, it is "common sense" to white-power racists that
whites are superior to blacks, and that those with brown skins
are mud people.
However, that "common sense" is obviously wrong.
