This doesn't happen in ratpoison.

Hi,
Does it happen every time or only the first time? Stumpwm caches the
binaries in PATH, so it should only be slow (albeit indeed very slow)
the first time.

This is a great optimization but I think it fails to look at the
bigger picture. It seems for all its awesomeness, the ansi standard
doesn't have a function to list the contents of a fucking directory!
Or at least not all implementations DWIM (I'm looking at you, clisp).
But I'm sure they each have a function in one of their extensions that
does that. So perhaps we should write a function in wrappers.lisp that
calls the right function for each implementation. Then, if needed, we
can just zip through the list and remove anything we're not interested
in (directories come to mind). That would hopefully be even faster.
Any takers?

I found this amusing so I thought I'd share. The same command run on 3
different implementations:
Lispworks:
ND> (length (directory "/usr/bin/*"))
864
SBCL:
* (length (directory "/usr/bin/*"))
815
CLISP:
[12]> (length (directory "/usr/bin/*"))
908

And THAT is why osicat exists. :)

Well shit we could just rip the code straight out of the
with-directory-iterator example! It sucks to add another dependency
but that looks like exactly what we need.

Actually, it's what CL-FAD exists for. OSICAT just surpasses the
implementation and goes straight to the OS, while CL-FAD is a
portability wrapper around DIRECTORY.
You could probably just rip CL-FAD:LIST-DIRECTORY.
