No, it's not elegant at all. mbox sources do still work, though. I only 
close the files in the child process. They remain open in sup's main 
process.

Setting the file descriptors to FD_CLOEXEC would be a cleaner solution, 
but I don't think that this works on Cygwin (or is accessible via Ruby).

That's a thought. If I get some time, I may be able to dig into this.
