Xander uses more ram per page load

[ITwrx]

when serving the hello world example from the Xander readme, Xander uses more memory for each page load.

Note: With only a "hello world" being served, it's easier to notice if you perform 10-20 requests and re-check the mem usage.

Also, if it's of any use, Jester has the same issue dom96/jester#270, but Prologue https://github.com/planety/prologue does not.
I'm guessing something in the stdlib changed a while back, and caused older implementations to have this issue?
Thanks
