Since a majority of malloc(9) uses immediately bzero(9) the allocation,
I added an flag to malloc(9) so one can ask for a zero'ed allocation.

This saves a couple hundred calls to bzero(9), improves cache-locality
and generally improves code readability as a result.

It will also allow us to operate a "idle-time-malloc(9)- zeroing-daemon"
later.

Never attribute to malice what can adequately be explained by incompetence.
