Would it be possible to read a value from the array and do something with it (e.g. send it to /dev/null)? Even a JIT shouldn't be able to optimize the value out

Would it be possible to read a value from the array and do something with it (e.g. send it to /dev/null)? Even a JIT shouldn't be able to optimize the value out if you're actually using the value, and as long as you're not zeroing secure memory all the time, the performance hit shouldn't be that large. This might cause side effects if /dev/null does not exist or is not the null device.
