Need network troubleshooting help

Is automatic memory management (acquire/release) done with just reference counting?

No... There's reference counting to free 99% of variables right away, but then it does a mark/sweep when idle or if it can't allocate any memory.

Ok, it's definitely an issue with references - see the r255 on the prototype here:

  #54[r1,l2] Name String [1 blocks] "httpCRq"    #55[r2,l1] NativeFunction 0x426706 (1) { 
      #56[r1,l2] Name String [2 blocks] "prototype"        #58[r255,l1] Object { 
          #59[r1,l2] Name String [2 blocks] "constructor"            #55[r2,l2] ...
 
        } 
    } 

It's being referenced a lot, but not unreferenced.

Looks like this could be a big issue with garbage collection, that when it frees things it isn't unreffing what they point to! I'll try and come up with some code to break it :)
