Btw, another aspect of this is user expectations: where we previously
were accustomed to the fact that listing files in a directory takes
some perceptible time, we are now "spoiled rotten" by the speed of our
CPUs and filesystems.  So the overhead incurred by Emacs-specific
processing, like reading from subprocesses, consing Lisp objects, and
GC, which 20 years ago would be insignificant, is significant now, and
users pay attention.
