No it is not. Re-read the OP question.

It may also depend on the implementation of threads. Some early
thread implementations in Linux or Solaris, for example, would
suspend the process when a thread waited, even if other threads
had something to do. (This shouldn't be a problem if you have
an up-to-date kernel, and are using pthreads, at least with
these two systems. But you never know.)
