no linter will be run twice for the same file.

### 4.xi. Will this plugin eat all of my laptop battery power?
ALE takes advantage of the power of various tools to check your code. This of
course means that CPU time will be used to continuously check your code. If you
are concerned about the CPU time ALE will spend, which will of course imply
some cost to battery life, you can adjust your settings to make your CPU do
less work.
First, consider increasing the delay before which ALE will run any linters
while you type. ALE uses a timeout which is cancelled and reset every time you
type, and this delay can be increased so linters are run less often. See
`:help g:ale_lint_delay` for more information.
If you don't wish to run linters while you type, you can disable that
behaviour. Set `g:ale_lint_on_text_changed` to `0`, and consider setting
`g:ale_lint_on_save` to `1` to enable linting when you save files. You won't
get as frequent error checking, but ALE shouldn't block your ability to edit a
document after you save a file, so the asynchronous nature of the plugin will
still be an advantage.
If you are still concerned, you can turn the automatic linting off altogether,
including the option `g:ale_lint_on_enter`, and you can run ALE manually with
`:call ale#Lint()`.
