| This package is used to replace framework functions with different |
| implementations at run time. |

| Local Modifications: |
| |
| reentryIsland is allocated in high memory with vm_allocate rather than the |
| heap with malloc by changing the allocation policy to kAllocateHigh. It |
| appears probable that putting the reentry island in the heap causes its page |
| to lose execute permission at some point under some circumstances, which |
| results in a crash on Lion. This modification is temoprary to simply test |
| out the theory. If proven, the code will be improved somewhat. |
