When #define QUICK_THREADS was introduced, for copying
some task data for a child thread, one proc_t pad byte
was used to mark, then later identify, those children.
Later the QUICK_THREADS was recycled as FALSE_THREADS,
and used for a different purpose, but a conditional in
the header file erroneously remained. Now, it is gone!
