/**
* @class TSS_Object
*
* TSS_Object base class for usage of TSS, supports asynchronous exits
* and cleans up the derived object if the thread that created it
* is closed or exits without (having a chance for) cleaning up.
*
* Provides registration and a cleanup handler for objects in
* thread-specific-storage (TSS). It should be inherited by all classes that
* are only valid within a certain thread. The cleanup handler ensures
* that the object will be removed if its owning thread died. For this,
* the derived object must call the constructor and should have a
* <b>virtual</b> destructor.

*
* @bug I disabled TSS because it led into too many problems.
* @see bug with id "libc/2650" of glibc !
