Need network troubleshooting help

Mhh, to me it looks like connection objects just don't get freed. After running one HTTP request I see the following if I do a trace():

 1[r2,l1] Object {
  #2[r1,l2] Name String [1 blocks] "ÿ"    #3[r1,l2] Object {
      #6[r1,l2] Name String [2 blocks] "timers"        #8[r2,l1] Array(0) [ ]
      #9[r1,l2] Name String [2 blocks] "watches"        #11[r2,l1] Array(0) [ ]
      #14[r1,l2] Name String [1 blocks] "net"        #12[r1,l2] String [2 blocks] "\x04\x00\x00\x00\x00ÿÿÿ"
      #15[r1,l2] Name String [2 blocks] "history"        #19[r1,l1] Array(2) [
          #20[r1,l2] Name Integer 0            #16[r1,l1] String [2 blocks] "echo(0);"
          #56[r1,l2] Name Integer 1            #36[r1,l1] String [16 blocks] "setTime(1.450337081404E9);var postUrl=\"http://h.voneicken.com:4567/temp\";var http=require(\"http\");var int1,int2;var errCnt=0;var okCnt=0;"
        ]
      #26[r1,l2] Name String [2 blocks] "modules"        #24[r1,l1] Object {
          #27[r1,l2] Name String [1 blocks] "http"            #23[r2,l1] ...
 
        }
      #297[r1,l2] Name String [2 blocks] "HttpCC"        #299[r1,l1] Array(1) [
          #332[r1,l2] Name Integer 0            #324[r2,l1] Object {
              #325[r1,l2] Name String [2 blocks] "__proto__"                #320[r2,l1] ...
 
              #329[r1,l2] Name String [1 blocks] "type"= int 1
              #328[r1,l2] Name String [2 blocks] "#onconnect"                #264[r1,l1] Function {
                  #265[r1,l2] Name Param "resp"                     undefined
                  #295[r1,l2] Name String [1 blocks] "ÿcod"                    #266[r1,l1] FlatString [29 blocks] "resp.on(\"data\",function(d){if(d!==\"OK\")console.log(\"Got unexpected response:\",d)});resp.on(\"close\",function(gotErr){if(!gotErr&&resp.statusCode!==\"200\")console.log(\"Got HTTP code\",resp.statusCode);if(gotErr||resp.statusCode!==\"200\")errCnt++;else okCnt++});resp.on(\"error\",function(err){console.log(\"HTTP response error: \",err.message)})"

I thought the connection gets removed from the HttpCC array here: https://github.com/espruino/Espruino/blob/master/libs/network/socketserver.c#L548 and I verified with a printf that this indeed gets executed. I must not be understanding something correctly...
