"There is an unspecified limit on the number of additional arguments that can be passed."
AFAIK, for C++11 implementations of std::thread, based on 30.2.1.2 of [1], the constructor is to make use of variadic templates. I believe that is where the term "unspecified" originates. For pre C++11 implementations, this can only be achieved through multiple overloads with a varying number of parameters, which would inevitably have a trivial upper-limit.
