path.module is costly in 4.6 if you have several hand added aliases
(like we had on a site for every node of a certain type). Grabbing the
whole list of aliases into memory, then getting and returning the array
on *every* call to the get_normal_path, and flipping the array on *every
call* to this function is extremely costly! The fact that pathauto is
costly is because path.module is costly itself with a lot of aliases.
Pathauto only helps you to quickly have these enourmous number of aliases.
