While I think Zack's solution is the right thing long term, IMHO the
author of the code would be in the best position to make this kind of
structural change (i.e. not me.)

What I'm willing to do is supply a patch to increase the FD soft limit
to the hard value.  I'd bet this will get around the problem for most
users and I'll file a PR referencing this discussion in case anyone
gets motivated to go with Zack's idea.
