Comment (by costdev):

 In Chassis, I ran a `microtime()` test between `copy_dir()` and
 `move_dir()` on `plugins/woocommerce`. Both `copy_dir()` and `move_dir()`
 included OPcache invalidation.

 Test 1:
 {{{
 copy_dir(): 18.564819812775
 move_dir(): 2.5664520263672 (86% faster)
 }}}

 Test 2:
 {{{
 copy_dir(): 17.737833023071
 move_dir(): 2.5115830898285 (85% faster)
 }}}

 Test 3:
 {{{
 copy_dir(): 17.455080986023
 move_dir(): 2.4744238853455 (85% faster)
 }}}

 I also tried swapping the order so that `move_dir()` came first, in case
 the first one would always run a bit slower. The results were the same.
