XPACleanup - release reserved XPA memory
#include <xpa.h> void XPACleanup(void);
When XPA is initialized, it allocates a small amount of memory for the access control list, temp directory path, and reserved commands. This memory is found by valgrind to be "still reachable", meaning that "your program didn't free some memory it could have". Calling the XPACleanup() routine before exiting the program will free this memory and make valgrind happy.
