Ummm, wouldn't you have a problem of two changers at the same time?
If they both get a copy, change it, then one gets the lock and commits
that change and the second then gets the lock and makes its change,
then you'd lose the first change.  Unless the change is to a single
line in the file, in which case it would be ok.
