sys/tree.h sys/queue.h are they threadsafe?

[Matthew Dillon]

They are not, nor should they be, since their use cases under SMP tend to
already hold a lock for other reasons.  If you think about it, even if the
core routines were thread-safe, the caller's use cases are not going to be
thread safe unless the caller uses locks around its own use cases anyway.
