I'll have to look at this carefully.  Given the ability to store the data 
directly in the void* might mean that this would be a viable replacement for 
thread_local_ptr<> (as in thread_local_ptr<> can just be a simple wrapper 
for a thread_local<void*>).  I simply hadn't thought of doing something like 
that.

I'm not a POSIX expert, but none of the books or documentation I've found 
describe any methods that allow you to print a pthread_t.  A quick web 
search shows only cases where someone passes an "id" into the thread for 
this purpose.  So, AFAIK, this isn't possible on *any* platform.  If I'm 
wrong about this, I'd like to know it.
