From: "John M. Sellens" <jmsellens> libfontd.a clobbered errno in two cases, and xdvi relies on errno==EMFILE to close a file and try again - this kept xdvi from working on machines with a low number of openable files and a large number of files in the dvi file. openfont() also changed to give up if the original open() fails for any reason other than ENOENT - we can't fix anything but a missing file.
