Of course. I read this line of the docs:

#:manager manager

but not this one:

manager   :   manager?
<https://docs.racket-lang.org/web-server/servlet.html?q=serve%2Fservlet#%28def._%28%28lib._web-server%2Fmanagers%2Fmanager..rkt%29._manager~3f%29%29>
      =   (make-threshold-LRU-manager
<https://docs.racket-lang.org/web-server/servlet.html?q=serve%2Fservlet#%28def._%28%28lib._web-server%2Fmanagers%2Flru..rkt%29._make-threshold-.L.R.U-manager%29%29>
 #f (*
<https://docs.racket-lang.org/reference/generic-numbers.html#%28def._%28%28quote._~23~25kernel%29._%2A%29%29>
 128 1024 1024))


which comes a page later given how many arguments serve/servlet has. I
still haven't internalized how to read the documentation properly. Seems to
suggest the default handler is #f, so that should be OK to do.

It also means that it didn't help much that I increased the current RAM on
my server. Good to know.
