ui_thread_is_dead is already a global variable.  How
is this different than "shared," and how do I designate
it as shared?

Under MSVC, *all* the global variables were shared, so
if one thread modified a global, the other thread would
see it.  That doesn't appear to be the case here.

The program is designed in such a way that all the global
variables are assumed to be shared between threads.  If this
isn't the case when using fork( ), I could be in for some
long nights. :-/  Is there a way to designate *all* globals
as "shared?"  (Or am I still missing something here?)
