Perhaps it would be best to take PHP out of the picture entirely after the
upload.
For example, upload to a temporary directory, and, as your last PHP step,
use http://php.net/rename to move the uploaded file to a "to_be_installed"
directory.
Then you can have cron job 2 minutes that installs anything it finds in
that directory.
At that point, nothing the user can do can interfere.
That wouldn't necessarily make the operation atomic...
What makes a "patch" atomic?...
You'd be looking at something like subversion for that, I should think...
I don't think even tar -xzf guarantees atomicity, but I dunno.
