Testcase for pthread_atfork() hang syptom on NPTL

Compile wit GCC using
  cc -o thread_wait_atfork2 thread_wait_atfork2.c -lpthread
and run it using
  ./thread_wait_atfork2

Output is as follows:
MAIN (1115036517): Atfork handler installed.
MAIN (1115036517): Thread #1 started.
MAIN (1115036517): Calling Lock()...
Thread #0 (1115036517): restarting child
MAIN (1115036518): Calling Lock()...
MAIN (1115036519): Calling Lock()...
MAIN (1115036520): Calling Lock()...
MAIN (1115036521): Calling Lock()...
MAIN (1115036522): Calling Lock()...
MAIN (1115036523): Calling Lock()...
MAIN (1115036524): Calling Lock()...
MAIN (1115036525): Stop signal received, waiting for threads to end...

Expected behaviour would be that there are messages from MAIN and Thread
**EVERY** second.
