Mark, can you see if this (and previous commits I've made) fixes the file
handle abuse problem you reported?

I tested this locally using "ulimit -n 200" to reduce the file handle limit
on my box from 8192 to 200. Before this change, I saw the same error you
did. Afterward, no error. Hoping you experience the same.
