Memory grows with each request

Thanks for your work on this!
When I tried your minimal example

import mofuw

proc handler(req: mofuwReq, res: mofuwRes) {.async.} =
  routes:
    get "/":
      mofuwResp(
        HTTP200,
        "text/plain",
        "Hello, World!"
      )

handler.mofuwRun() # default listening port: 8080

in release mode and debug mode on windows 10 and
Nim Compiler Version 0.18.0 [Windows: amd64]
I recognize that the memory grows with each call to http://127.0.0.1:8080/ (~80kb per 10 times pressing F5 in browser) and then stays at this size until I do next call. I have the feeling, when I do enough calls, the memory is filled completely.
Am I doing something wrong? Should I manually free the memory?

Update: The memory went down to 1.6mb again, maybe this was due to open connections or a time related setting.

Could be related to this one (windows only):
nim-lang/Nim#5589

This problem may be a problem with Nim, but you need to have Issue open until you solve it

I now tested it using wrk and it seems to work good for a high amount of connections (similiar to jester), so it was no problem. Sorry for the trouble.
