<TT>GC_add_to_black_list_normal</tt>.
A page black-listed in this way may appear inside a large object,

<P>
The <TT>GC_allochblk</tt> routine respects black-listing when assigning
a block to a particular object kind and size.  It occasionally
drops (i.e. allocates and forgets) blocks that are completely black-listed
in order to avoid excessively long large block free lists c
