Comment (by nextendweb):

 I proprose 36455.7.diff:
 - the filter in the previous patch is not necessary in my opinion. I do
 not see any kind of usage of that as if a plugin/theme/wordpress gets
 updated, just other plugins/themes/(previous wp version) could exclude any
 file.
 - Optimized {{{function_exists( 'opcache_invalidate' )}}} call to run only
 once per install
 - Added {{{.phtml}}} file extension as it is very popular. Consideration:
 These are valid file extensions for PHP, but I think they are very rare:
 {{{.php3 .php4 .php5}}}

 BTW: I'm thinking about that maybe it would be better to call
 {{{opcache_invalidate()}}} on the deleted PHP files also before the
 deletion. Maybe that would be a more safe way of clearing the opcache.

 Also I think none of these steps solve the issue when the user just
 uploads(ssh,ftp,sftp) the update/plugin/theme directly and in that case
 the site still can crash because the invalid cache state.
