Andy Ross 83d1ca06dc tests/mem_protect/stackprot: Need a delay under SMP 
The "alternate thread" test would spawn a thread and then exit the
test, but on SMP that other thread runs asynchronously and it was
possible for the main thread to exit the test entirely before the test
thread had a chance to run (and overflow its stack), leading to
spurious test case failures.

Obviously we can't exactly synchronize to an async crash, so put a
short delay in after spawning the thread.

Title: Stack Protection Support

Description:

This test verifies that stack canaries operate as expected.

--------------------------------------------------------------------------------

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info

--------------------------------------------------------------------------------

Sample Output:
tc_start() - Test Stack Protection Canary

Starts main
Starts alternate_thread
alternate_thread: Input string is too long and stack overflowed!
