This is trivially to reproduce on OpenBSD with a small number of file descriptors available.  In my browser I set the ulimit -n to like 60 and open up a ton of tabs and it'll bomb.  I agree though this patch only makes it a little better and in other cases it'll bomb elsewhere in the font code.  Even though this helps it isn't a fix so it should be disregarded.  What seems to be the root cause is file descriptor starvation but I have not been able to locate where this cascades into this (and many other similar crashes).
