For another patch I had a look at the PHP docs to see what it does and 
how it can influence speed.
The "@" actually only temporarily sets the error reporting level to 
zero. Error handlers are called as usual and nothing is changed to the 
handling of the code.
Checking if a file exists first is rather cheap (it's also cached) and 
will prevent the whole error handling to take place (which won't have 
any result except for burning CPU cycles).
