Just think about your case:

the file is being updated. That means it is not complete.

Depending on how the update software works, you can either read a file of zero
length, or an incomplete file.

What will happen if PHP reads/executes a class file of zero lenght? The class
definition is missing, fatal.

What will happen, if PHP reads/executes an incomplete file? A syntax error, fatal.

What you must do:
- make sure the class file is not read/executed during update.

What you can do:
- speed up the upgrade process (upload to some other file and copy locally, ...)
