+/*++ @file
+ Since the SEC is the only program in our emulation we
+ must use a UEFI/PI mechanism to export APIs to other modules.
+ This is the role of the EFI_EMU_THUNK_PROTOCOL.
+
+ The mUnixThunkTable exists so that a change to EFI_EMU_THUNK_PROTOCOL
+ will cause an error in initializing the array if all the member functions
+ are not added. It looks like adding a element to end and not initializing
+ it may cause the table to be initaliized with the members at the end being
+ set to zero. This is bad as jumping to zero will crash.
