Wrong HTTP Content Length for Reader when "show-time"...
It is not possible to fix this problem as once the content length is written it can't be changed later on. So if e.g. the content comes from the cache, the cache sets the content length and this can't be overwritten anymore. These are the times, where it goes wrong - the same applies to the reader.
But as "show-time" is only a debugging feature, this is not a real problem, so we set it to "WONTFIX".
There is a way to fix it: Wrap response, and when content length is set add a fixed amount (equal to max length of time string) to it to reserve space for the time string. Once time string is written, add some padding so actual content length matches advertised.
But it might not worth the trouble adding all this complexity just to implement some debug feature
