Title: C++ Synchronization
Description:
The sample project illustrates usage of pure virtual class, member
functions with different types of arguments, global objects constructor
invocation.
A simple application demonstrates basic sanity of the kernel. The main thread
and a cooperative thread take turns printing a greeting message to the console,
and use timers and semaphores to control the rate at which messages are
generated. This demonstrates that kernel scheduling, communication, and
timing are operating correctly.

Building and Running Project:
This kernel 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:
Create semaphore 0x001042b0
Create semaphore 0x001042c4
