The program I'm running has a thread per websocket. Running `valgrind --tool=massif` showed the websockets were using most of the memory. The websocket library I use is [niv](https://github.com/niv/websocket.nim). This is with the ORC mm.
When I use -d:useMalloc as a Nim compile flag, the leak is gone. For now I'm not planning to trace the leak any further. Could this be from an ORC mm bug?
