I think so. Here's a quote from a previous post I made on the subject:

"The reasons [for using tss in the thread class's implementation]
are two-fold: 1) The thread class becomes a handle class
that holds a reference-counted pointer to a thread_data class. When a
thread class is created, it gets access to the thread_data class for
the thread using TLS. 2) As you might guess from the name of the
thread_data class, there is other information associated with each
thread; for instance, a thread id, a flag indicating whether the
thread
has been cancelled (yes, there is an exception-based implementation of
thread cancellation), etc."
