// be called again. This is an extension to the spec that is possible with
// SuiteSparse:GraphBLAS but not available via a documented function.
// Instead, an internal method is used. If this flag is set, the next call
// to any @GrB mexFunction will first call gb_usage, which calls GxB_init
// to re-initialize GraphBLAS. That method will re-load the hash table
// with all PreJIT kernels.
// These 2 lines are placed together so a "grep GrB_finalize" reports
// both of them.
