Oddly perhaps, Unix has never really provided shared writeable files.
Perhaps there are good theoretical reasons for it; perhaps it was just
one of those simplifying assumptions that Unix was born with, I don't know.
That's why access to shared writeable resources are controlled by a
server, like CVS or svn or mysql. It's why you don't print using cat >
/dev/lpr.
People seem to want to do things like this--they keep asking for
applications to mediate between users editing the same file, like
Windows does it, but I wonder if it's such a great idea.
