Hello Michael,

Just a couple of comments on the fix:

1) The stream-low-level-lazy, ...strict, ...delay and ...force
    implementations have a pretty serious bug.  This bug was discovered by
    Alexandro Forero Cuervo and discussed on the SRFI-45
    list (with some spillover to the SRFI-40 list).  I posted a
    fix - please see the patched SRFI-45 document for the details.
    (also, AFC posted a patched version of SRFI-40 incorporating
    a version of the fix to this list).

2) I believe the discussion of stream-unfoldn in the first
    part of the implementation section was obsoleted by the
    SRFI-45-style promises (indeed, the actual implementation
    below it was then changed back to using the naive
    version, which should be correct and safe for space).

Regards
Andre
