  It requires a mutex.

  Only parsing is thread safe (and assuming the library got compiled
with the adequate options). Putting locking at the tree access level
would put a terrible burden on apps not requiring it. It's both simpler
and more efficient in most case to let the application do the locking
to protect concurrent tree accesses.
