I don't know what to say about it being impossible that other filesystems work
better.   Because FreeBSD doesn't support R/W ReiserFS, I used a USB thumb
drive both formatted and populated (with the python script) on a Linux system. 
 And with the case of unionfs, I simply had a FreeBSD Jail that shared the
underlying ZFS directory structure.

In both cases, the find command successfully reported the existence of all
300,000 subdirectories.
