Well, I wouldn't say that there is no reason; I can see that there are  
situations where it's useful. Whether it's something that's necessary  
is another matter; I'd say probably not.
I also don't know how big the overhead of TLS is in practice, so I  
don't know whether it's significant compared to file I/O or not.

I was actually mistaken here: that isn't in issue. I was confused by  
all the conditional compilations in tls.c.
