lementation probably performs
better in the uniprocessor case, but does not support thread operations in the
collector.  Hence it cannot support the parallel marker.)
<P>
All implementations must
intercept thread creation and a few other thread-specific calls to allow
enumeration of threads and location of thread stacks.  This is current
accomplished with <TT># define</tt>'s in <TT>gc.h</tt>
(really <TT>gc_pthread_redirects.h</tt>), or optionally
by using ld's function call wrapping mechanism under Linux.
