Problem:

Defect code :  2. Omission

Two problems. The first one is "the same thing" as with the
pthread_cancel(). It's reported in "alt-pthread_cancel-2003-04-04" 
DR of mine. Please see that DR for details. The second one is that 
<quote> there really should be no restrictions on pthread_exit that 
don't apply to cancellation -- they're effectively the same

(Subject: Re: cancellation during cleanup handler execution)

sorry for a google reference, I just can't resist.

Action:

1. Insert the following wording (or something like that) at 33028
(after "...unspecified order."):

<insert>

Before cancellation cleanup handlers followed by thread-specific 
data destructor functions are executed, the thread's cancelability 
state shall be set to PTHREAD_CANCEL_DISABLE and thread's 
cancelability type shall be set to PTHREAD_CANCEL_DEFERRED.

</insert>

2. Insert the following wording (or something like that) at 33036
(after "...pthread_exit()"):

<insert> or cancellation processing </insert>
