Currently, there is a conversion from float64 to int64 when returning the duration needed to accumulate the required number of tokens.
When limiters are set with low limits, i.e. 1e-10, the duration needed is greater than math.MaxInt64.
As per the language specifications, in these scenarios the outcome is implementation determined.
This results in overflows on amd64, resulting in no wait, effectively jamming the limiter open.

Here we add a check for this scenario, returning InfDuration if the desired duration is greater than math.MaxInt64.

Fixes golang/go#71154

These days people will just import the packages and the go tool will
do the right thing. We don't need to explain it.

Add a pointer to the git repo, though.
