An unfortunate mistake: DIRECTORY used stat() on all entries in a directory,
not only those that matched the mask. It was just a matter of switching
lines. Now things are better. Thanks a lot for reporting.

$ echo '(directory "/Users/jjgarcia/tmp/")(quit)' > foo.lsp; sudo dtrace -n
'pid$target::safe_stat:entry  { printf("%s\n", copyinstr((uintptr_t)arg0));
}' -c "ecl -norc -load foo"
dtrace: description 'pid$target::safe_stat:entry  ' matched 1 probe
;;; Loading #P"/Users/jjgarcia/foo.lsp"
dtrace: pid 39532 has exited
