Anyway, it does compile (gcc 3.3.5 + linux 2.6.11 + x86_64) and it does
its work pretty well for my own personal needs. I never claimed it was
complete or portable, nor did I claim it was conformant and I will never
claim it is the best and only implementation.

The point is I answered a simple question with simplicity. My skeleton
allows Mr. JackC to work with thread and objects in an easy way, further
more I sticked to the logic I (believe I have) found in the code sample
in the original post and tried my best to Mr. JackC understand mine.

It is a shame so many people here are not able to understand not
everyone in this world is a C++ guru or theorician.
