Subject: Re: Too many open files on OpenBSD

Hello Edd, an OpenBSD user here too.

The error messages speaks of more than 3055 recursion levels. Not
every level is a call to parse, but if you take out the #new and #each
methods I'm sure there are a lot more than just 5 files opened at the
same time.

Are there that many dependencies? I don't think so. I haven't seen
those .tlpsrc files yet. I'll take a look.
