the simplest example that comes to my mind:

1 user a checks out directory d.
2 user a adds a file to directory d
4 user b deletes file x in the directory d and changes some files in
directory e that used to depend on file x (--> this is a change to the
directory)
5 user b commits his changes
6 user a commits his add

If the directory is updated after user a commits, he would have to deal with
the changes that he recieves but never asked for (the delete of file x).
Especially, since this is a partial update only, he might run into build
problems, as he still has the old version of directory e with the files that
depend on file x. So now, he has to update his whole WC to get a working
version, which might incorporate even more changes that he doesn't want to
cope with at that moment.
And all of this just because he did some minor commit? This is why
"autoupdates after commits" are regarded 'A bad thing (tm)' and I prefer it
the way it's right now.

Allowing this behaviour to be turned off with a switch would not help, as
user a would need to check the log before committing, otherwise he'd have no
clue that he might recieve changes. And even with checking the log, he might
not be shure as there is a short window between him checking and him
committing in which someone else might commit.
So the default behaviour would have to be 'autoupdates off' and a flag to
turn it on. There's no need for that however, as you can easily write a two
lines script that does exactly that - commit and update the current
directory.

The primary reason is: I want to update when I'm ready to deal with any
conflicts arising from my own actions.
