Because of their dynamic nature, if they are bound by a thread, they can safely be used by that thread afterwards without interference, indeed, as their binding becomes thread-local. If however a dynamic variable is used without local rebinding, you might need to also protect their access using a lock depending on how you use them (this then allows process-shared objects to be shared among threads and accessed like globals). If you however want to create them from a thread using defparameter/defvar, I'd have to check but my guess is that ECL uses the necessary locks internally for its own package/symbol management. My experience is with special variables to be created before the other threads are launched.
