m4_p([dnl
In previous releases, applications set the priority of a database's
pages in the m4_db buffer cache with the DB-__GT__set_cache_priority
method.  This method is no longer available.  Applications wanting to
set database page priorities in the buffer cache should use the
m4_refT(memp_set_priority) instead.  The new call takes the same
arguments and behaves identically to the old call, except that a
m4_ref(DbMpoolFile) buffer cache file handle is used instead of the
m4_ref(Db) database handle.])
