Sounds fine. I don't know of any importance for SessionExpire to apply
before you delete the session; it's basically the same either way.
You can use the -mtime argument to find to specify days if you fine -mmin
+2940 to be too obscure. :)

I wouldn't recommend it unless you have a real reason. Sessions stored in
files on a local filesystem are generally the most efficient and easy to
manage and prevent fewer locking difficulties than DBM or MySQL with
MyISAM tables.
