Description of problem:
Memory locations returned by pthread_getspecific are not zero'ed
across pthread_key_delete/pthread_key_create calls, as stated in the
documentation "The value initialized associated with the returned key
 is NULL".

The result is that a new key returned by thread_key_create /
pthread_getspecific will not be initialized to zero if:

     ((the area was freed by a pthread_key_delete) and
     (when freed the pthread_getspecific area was not NULL))

This problem happens on AS 3 when NPTL is not used
(LD_ASSUME_KERNEL=2.4.1).

The problem does not recreate on AS 3 when NPTL is used 
(LD_ASSUME_KERNEL=2.4.20 or not setting LAK).

The problem was does not appear to happen on AS 2.1 

Please see the Sample_Run (attached below) for more details.

Version-Release number of selected component (if applicable):
glibc-2.3.2-95.20.i686

How reproducible:
Always

Steps to Reproduce:
1. Extract attached files
2. Build program by running "make"
3. Run program using NPTL: "LD_ASSUME_KERNEL=2.4.20 ./getspecific" (works)
4. Run program without NPTL: "LD_ASSUME_KERNEL=2.4.1 ./getspecific"
(fails)
    

Actual Results:  see attached file "Sample_Run"
