Hello all,

Chris K. Jester-Young has been hard at work getting his SRFI-41
implementation ready in time for Guile 2.0.8, and I think it might be
ready to push.  What do you think?

Reviews solicited.

PS: Although I put cky's name on this commit (he's certainly the primary
    author), I made some tweaks to it since he last looked at it which
    he may or may not approve of :)
