Ok. That would require passing each peer's HWM to the other peer. So 
that both can compute and use sum HWM instead of the original local HWM.

In short:

1. There's ctx_t::register_endpoint function which register inproc 
endpoint with the context. We can store bind()er's HWM there.

2. When connect()er retrieves the ednpoint, it would get bind()er's HWM 
along with it, it will add the two HWMs and initialise the newly created 
pipe accordingly.
