I share your statement partly, because ...

... this was limited up to 31998 directories in an ext3 fs.
mkdir: cannot create directory `31999': Too many links
mkdir: cannot create directory `32000': Too many links
and so on...
I tested the same thing on an xfs fs and the interesting thing was that
I got further...
Creating {1..63000} wasn't any problem,
I also added these dirs in the same directory without a prob:
for i in {1..63000} ; do mkdir abc${i} ; done
for i in {1..63000} ; do mkdir def${i} ; done
I didn't want to spend more time on testing.
It took me a whole lotta time to delete that stuff. ;-)
Maybe under xfs directories just are limited by inodes and nothing else.
Both cases, ext3 and xfs, were tested on an x86_64 (Dual xeon).
