Details:

In find version 4.3.1, the fts-based version of find works very slowly on
NFS.  In this example, it's well over 20 times slower:-

$ time oldfind-dev    /dir -maxdepth 2 -name wireless
[...]
real    0m3.348s
user    0m0.004s
sys     0m0.060s
$ time find-dev /home/build -maxdepth 2 -name wireless 2>/dev/null
[...]
real    1m47.342s
user    0m0.064s
sys     0m0.624s

Using -O3 doesn't help.  It looks like the fts implementation stats
dramatically more files.
