I'd missed your point earlier!!!  I was calling pthread_join with the address
of the thread rather than the thread itself...

That's all I needed.  My experience is very stale w/ C & C++, but why didn't I
get at least a compilation warning when I passed the reference to the thread,
rather than its value?

I.e.
    pthread_t thread;
     <snip>
    retVal = pthread_join(thread, &threadExitStatus);

*AND*

    pthread_t thread;
     <snip>
    retVal = pthread_join(&thread, &threadExitStatus);

both compile with no warnings or errors (using g++ -W -Wall
-Wno-non-virtual-dtor -Wwrite-strings -Wpointer-arith -Wnested-externs
-Woverloaded-virtual -Wbad-function-cast -ansi -pedantic).
