Looks to me like krb5int_thread_detach_hook should mostly be doing  
that.  It's the handler in the support library, but all our TSD use is  
funneled through some bookkeeping in the support library, to improve  
things on platforms where OS handles (TLS indices, pthread keys) on  
TSD may be a limited resource.  It ought to be deallocating any  
registered per-thread data, though it looks like maybe the bookkeeping  
data itself isn't properly freed.
