I did a quick stress test of both versions (with and without executor 
specified) and don’t see any difference in how many requests can be handled. 
Probably good to keep thread usage to a minimum, I'll update that.

I think this code has the effect of creating one thread for the selector and a 
second one for the execution of the handlers. If we want to keep thread usage 
to an absolute minimum then it might be better to not set an executor. Then, 
the selector thread executes the handlers as well.

The problem I was referring to was not about printing to the console. I hadn't 
thought about that, I agree the default locale should be used there. I was 
referring to `Last-modified` HTTP headers with a non-English date value, e.g.:

Last-modified: Di., 21 Sep. 2021 09:56:53 GMT

I think browsers will get confused by this. It probably isn't a big deal since 
I think the server doesn't implement conditional GETs (i.e. use the 
last-modified date in subsequent requests), but the HTTP spec is [quite strict 
][1] about date formats.

Shouldn't we filter paths that are not readable here too? There's no point in 
printing a link that will result in 404, is there?

Hmm... When printing messages on the console don't we want a localized date? Or 
are you referring to other usages of the date formatter?  Worth double checking

I think this and other usages of `DateTimeFormatter.ofPattern` need to be
