A concurrent `put` and `popFront` will do nothing to avoid races 
in `Queue`.
Individual access to _offset is atomic but its point of use in 
both put and popFront is not.

Both functions look like this:

    1. Atomic-read-offset
    2. Anything can happen
    3. Atomic-write-offset

If one function has completed 1) then other has completed 1+2+3 
then you get a race.
Chaining two atomic things doesn't make the whole atomic, rather 
classic mistake with mutual exclusion.
