on both 6.8 and 7.3:

	development environment: ulimit -n = 1024
	  installed environment: ulimit -n = 4096

With a basic sampling of file descriptors

	while true; do
	    lsof -P -M -l -n -d '^cwd,^err,^ltx,^mem,^mmap,^pd,^rtd,^txt' -p -u 
$USER -a | wc -l
	    sleep 2
	done

the total number of file descriptors for $USER increases only by about 600.
