It's not urgent. In fact, I'm not convinced we need to even increase
the current comm[] size, since for normal user programs the main way
'ps' and friends get it is by just reading the full command line etc.

But I think it would be good to at least do the cleanup and walk away
from the bare hardcoded memcpy() so that we can move in that
direction.
