 I don't see that happening. What OS are you on? How are you detecting
open file handles?

 On my Linux box if I use "lsof" before and after reading a shapefile
(with readOGR) I don't see any new file handles left open.

 If I open a file connection with "file" and "open" I do see a new
file handle, so if readOGR was leaving it open then I think I would
see it.
