Review comment:
The `startTime` is set once at the beginning of the method while the
`attemptStartTime` is initialized just before the first attempt and then
updated again after every iteration. So the `attemptStartTime` is always
greater than the `startTime` and therefore the quantity being added to the
`timeoutMs` here is actually negative.
But I see how that's confusing, I'll refactor the expression to make this
more clear
