FWIW:
I used to routinely do the recursive search into lower directories as you 
show in your warning.

I have been totally destroyed by too many open file search handles under 
Win95/98, NT version <= 3.51 or when searching on a Novell system.  The 
worst ones were Novell and when networked with NT.  Occasionally everyone on 
the network would lock up!
