One can reproduce the problem with this repo.

We know the problem is caused by pipelining, especially when maximal pipelining depth is heigh. Some ideas to simplify the repository:

1. eliminate cpsVar
2. swap doneVar for an MVar
3. eliminate Channel and use connectPipelined instead,
4. eliminate usage of typed-protocols, and run ChainSyncServer against ChainSyncClientPipelined against each other with: directPipelined.
5. simplify chain-sync protocol

We found out that the memory leak was resolved when the number of pipelined messages was reduced to a small number. There's more information about it in an unfortunately private slack thread.
