Screen Lock Captures Desktop

Every time my system kicks into screen lock mode, it first takes a snapshot of the desktop and then uses that as the screen lock background. This wouldn't normally be much of an issue except it's on a sensitive/classified system. Any ideas?

pthread_spin_unlock

pthread_spin_unlock(3C) 				   Standard C Library Functions 				   pthread_spin_unlock(3C)

NAME

       pthread_spin_unlock - unlock a spin lock object

SYNOPSIS

       cc -mt [ flag... ] file... [ library... ]
       #include <pthread.h>

       int pthread_spin_unlock(pthread_spinlock_t *lock);

DESCRIPTION

       The  pthread_spin_unlock()  function  releases  the  spin  lock	referenced  by	lock  which  was  locked with the pthread_spin_lock(3C) or
       pthread_spin_trylock(3C) functions. The results are undefined if the lock is not held by the calling thread. If there are threads  spinning
       on the lock when pthread_spin_unlock() is called, the lock becomes available and an unspecified spinning thread acquires the lock.

       The results are undefined if this function is called with an uninitialized thread spin lock.

RETURN VALUES

       Upon  successful  completion,  the  pthread_spin_unlock()  function returns 0. Otherwise, an error number shall be returned to indicate the
       error.

ERRORS

       The pthread_spin_unlock() function will fail if:

       EINVAL	       An invalid argument was specified.

       EPERM	       The calling thread does not hold the lock.
