That ("nasal demons") has got to be one of the most enduring, and
amusing, legacies Chris Torek has given the world. (His stdio is
probably more _useful_, but not nearly as amusing. :)

Seems to me that each of these is a bug that should be fixed (one, that
the dynamic linker is willing to load the same library in multiple
major versions; two, that multiply-defined symbols are silently
resolved randomly to one or the other definition).
Neither one would make things _work_, but at least they'd make things
fail at dynamic-link time, rather than just breaking in weird and
wonderful ways at run time.
