Alternatively, provide some sort of flow-control back-pressure to slow
down the source of the channel..

For instance, if the data for the outbound direction of a channel
comes in on a reliable byte stream IPC channel of some sort [1], and
you run out of window on that channel, stop reading from the data
source.  The OS will provide buffering and/or back pressure to the
other end of that channel; when the channel's window reopens, you can
start reading that channel again..
