| Tensorflow uses its on implementation of ashmem_create if it is |
| not being built for Android. |
| |
| That implementation has a bug, where if the same 'name' is passed in |
| for multiple invocations, it will resize the underlying shared memory |
| file, effectively ignoring the 'anonymous' aspect expected of ashmem. |
| |
| Our implementation handles this better, and this ensures all of the ashmem |
| functionlity is consistenly served from our implementation. |
