The patch *does* speed up, even if it's not that much ..

This array is pretty small, a full cached page has less then 20 entries, 
a non cached page access probably not more than 100 (my intro package 
test has 40 entries non cached), let's calculate with 200: If a typical 
classname is 30 chars long (30 bytes), memory consumption will be: 
30*2*200 -> ~12kb, maybe plus some bytes for a btree in php on the array 
keys. Imho we can afford this.
