Regardless, in either case it doesn't mean that this problem can't
happen unless there is a problem with hardware or network, and just
because other impls are using established libraries, it doesn't mean
there are not going to be bugs which affect subversion and cause
checksum problems. I can cause it manually with svn move, let the
file move to a new location, then copy the file manually back into the
directory I moved it from and try to commit. That would cause a
checksum (at least it did last time I tried it which was a long while
back) and that is caused by user error, since the user is not supposed
to do that, and if you've worked with CVS for a long time, this is the
first thing you think of doing to revert a change or undo a move.
