Howto implement atomical actions

Hi all I am developing a web interface to patch a program. The user uploads the patch and after uncompressing and verification of signature, the update should take place. However I do not want users to be able to start an update and then abort the process by stopping to load the page. I imagine that by calling a program externally from php that it would be possible but there are limitations because of the distribution. The systems are installed on php+mysql+apache servers but no shell access is granted. I greatly appreciate help in this matter.
