There is the potential here for a enhancement to Mac OS X, where the
application files are locked as part of invoking the application. This
sort of transparent and distributed locking is comparatively rare in
Unix environments, but there are operating systems where this locking
does occur.
Various attempts include:
http://freshmeat.net/projects/dlm/
http://opendlm.sourceforge.net/
Basically, the application activation would lock down the file(s) (or
bundle) associated with the application, preventing modifications.
Some form of locking is likely present in the Xsan file system support,
I'm not sufficiently familiar with that to post a reference.
I'd have to say that this particular sequence and this locking would be
rather low on my list of application priorities. It's in the "if it
hurts, don't do it" category. And yes, we do all have to deal with the
sheer creativity of our user base. And once in a while, such creativity
will cause the application to tip over.
