** Source: test7.c (DuplicateHandle)

** Purpose: Tests the PAL implementation of the DuplicateHandle function,
** with a handle from CreateThread. The test will create a thread
** handle and its duplicate. Then get the priorities of the threads,
** set the priority of one and the change should be seen in the
** other.
