So, it would be in the best position to do something instead of just quitting graciously. You later suggestion "leave the working copy in a state of mixed revisions" is exactly what I as user would expect from it: "hey, error! I couldn't finish my job bcoz file X is in use, just close the other app then try updating again". 

Dito. That context knows that it encountered a problem and knows best what
it's been doing, thus it's obviously within its own scope and *responsibility*
that it should be doing (or at least attempting to do) proper cleanup.
Necessity of "svn cleanup" should definitely be relegated to exceptional use cases,
since it's a problematic *foreign* intrusion into the lock-shared processing.
Well, so much for idealistic speak - I don't know SVN implementation
specifics which might go against implementing it like that.

> And I could swear it was like this before, I never had to cleanup even though I always forgot DLLs in use... I just can't test it because the only machine with a 1.6 SVN I have is a server and doesn't have Word (and will never have) - any idea how to mark a file "in use" on Windows Server 2003? Notepad/Wordpad doesn't cut it.

Probably see exclusive sharing modes (flags at Win32 CreateFile() API).
Either code up a quick app which locks a file, or do an internet search on
the terms encountered in CreateFile() docs and thus discover some app
which already does that, too.

HTH,
