Greetings,
I find myself coding some more in DrRacket on my local Win10 PC.
The finished program is to be run on a remote linux server.
I like to keep the code set up for the production environment
but to test it locally I need to configure some things differently.
Currently I'm doing this manua

"threading" is not included in the default racket installer, so
how do I get it?

As I went through these pains myself during the last 36 hours,
I want to offer a big THANK YOU for doing
Racketeers,
how much effort would it be to keep a rsync'ed copy of the files
relevant for the end-user on another machine? Then you could
make (require (planet...)) a bit smarter to check a list of server
(mirrors) for the packages and the impact on racket users would
be minimized.

As reference, lets run racket with 10 sec GC loop waiting for input:

Good, that means it is interesting :-)
Is there a way to increase the major GC frequency? It would make
investigating this a lot faster if it occurred every few seconds
instead of the default setting that it has now.
Hi,
today I was dabbling around with my servlet study, and switched
on debugging output for racket.
ste...@g128 racket % racket -W debug -u vacation-loop.rkt
GC [minor] at 1484840 bytes; 644984 collected in 1 msec
GC [minor] at 2219568 bytes; 650160 collected in 1 msec
GC [minor] at 4256
Final question for today:
Are stateless servlets supposed to be "forgettable"?
Using stateful servlets I can use e.g. redirect/get/forget
to render a concluded "session" (relatively) inaccessible.
Is there a similar mechanism for stateless servlets that I
am just not seeing?
Thanks,
s.

Hi.
In the web-server related documentation, I see the preferred way to
create local procedures as
(define (start request)
(local ((define (response-generator...))
(define (some-handler...)))
(do-something-with-these)))
Another way to create local procedures is

I can't create a stateless servlet in racket 5.0.2 (gentoo amd64).
I _can_ create a stateful servlet with

(make-threshold-LRU-manager
(lambda (request)
