I have multiple files of `.zcompdump` , why do I have multiple files of these?

I added this line to the ~/.zshrc above the source $ZSH/oh-my-zsh.sh line:

export ZSH_COMPDUMP=$ZSH/cache/.zcompdump-$HOST

Then, when we source $ZSH/oh-my-zsh.sh, the compinit command dumps to that new location.

Here’s where compinit is in oh-my-zsh.sh.
