[BUG] Unhandled exception in async proc when aborting the request on download

[2-towns]

Using the Codex App, when the request is aborted, the node crashes with the following error:

ERR 2025-03-07 12:23:50.171+01:00 Unhandled exception in async proc, aborting topics="codex" tid=737202 msg="/share/home/arnaud/Work/codex/nim-codex/vendor/nim-chronos/chronos/apps/http/httpserver.nim(1422, 15) currentStategensym857 == HttpResponseState.Empty Response body was already sent [Failed]"`

Could be related to #685 but it was already fixed.

Can't reproduce it with a simple manual test

dd if=/dev/urandom of=upload.bin bs=1000M count=1

timeout 3 curl -X POST localhost:8080/api/codex/v1/data \
  -H "Content-Type: application/octet-stream" \
  -H "Expect: 100-continue" \
  -T upload.bin

And 100 checks passed as well

# Run
curl -s https://get.codex.storage/testnet/run.sh | bash -s -- --storage-quota=100g

# Check
for run in $(seq 100); do
  echo "${run} - `date`"
  dd if=/dev/urandom of=upload.bin bs=100M count=1 2>/dev/null

  timeout 1 curl -s -X POST localhost:8080/api/codex/v1/data \
    -H "Content-Type: application/octet-stream" \
    -H "Expect: 100-continue" \
    -T upload.bin
done

You can try on this URL:

Start a download then cancel it.

Aha, got it - it happens on download ⏬

# Get file
curl -O https://fsn1-speed.hetzner.com/100MB.bin

# Upload
curl -s -X POST localhost:8080/api/codex/v1/data \
  -H "Content-Type: application/octet-stream" \
  -H "Expect: 100-continue" \
  -T 100MB.bin

# Download
