>Description:
	Someone ran:
	perl -e 'while (mkdir "x") { ++$n; print "\r$n"; last unless chdir "x"; }'

	Which leaves me with:
	rm -rf x
	rm: fts_read: File name too long

>How-To-Repeat:
	See Above.

>Fix:
	Since it was a small filesystem, I dump'd, newfs'd and restore'd. 
	But I thought maybe it was something that could be tweaked.
