Thanks for tracking this one down.  I usually only run "./check-guile
srfi-18.test"; I never looked seriously into this file.  There's a bit
of a mess here and elsewhere in the test suite about modules and paths,
but I did add a comment.

FYI in the upcoming Guile 2.2 (and already in the prereleases),
thread-terminate! should be much more reliable.
