Back on form

[sawyl]

After a good few days of being mojo-less, I finally fell as though I'm starting to cycle back up again. I've managed to break an annoying Pyrex problem that has been bothering me for a while: it turned out all I needed to do was change a couple my ctypedef lines to include the member names of the structure components I wanted to access. Once I'd got that done and once I'd fixed a leaking file descriptor problem by replacing a simple recursion with tail recursion, everything fell into place like a charm.
