If operation is JitMapOperation_MapOwner, permission must be RW-.

For [[#MapJitOperation|MapJitOperation_MapOwner]], memory permission must be RW-.
   −
If operation is JitMapOperation_MapSlave, permission must be R-- or R-X.

Operations [[#MapJitOperation|MapJitOperation_UnmapOwner/MapJitOperation_UnmapSlave]] unmap memory that was previously mapped this way.
    
This allows one "secure JIT" process to map the memory as RW-, and the other "slave" process to map it R-X.
