I never said I want a fail-safe cleanup. The spec never said that I 
shouldn't use TSD destructors for releasing non-local resources. Spec
just said that at thread exit the TSD destructors are called. I am
free to use them no matter how stupid it may sound. Thus you cannot
decide for me.

BTW, one reason why you may want to release even process-local 
resources is to keep memory checkers calm.
