Comment (by TimothyBlynJacobs):

 > My impression of the conclusion is that if there is a server resource
 issue that occurs a result of the zip creation process then a simple page
 reload brings the site back to it's previous state showing a plugin/theme
 update being available.

 I think this is accurate. But the failure happening _during_ the zip
 process specifically is not my big worry, but that it consumes resources
 so that when the file transfer happens, the site no longer has enough
 resources to complete the upgrade. Which is how you can end up with a
 fatal erroring site.
