Actually, libltdl is documented as being thread unsafe.  It offers a
way to use user-supplied locking functions so it could become thread
safe.  Unfortunately, the definitions for these user-supplied locking
functions don't match what is available from POSIX threads (the
locking must be re-entrant on a per-thread level) so it is not as
easily used as it could be.
