channels (the libthread variety) may pass by reference or value.
so passing by reference or value is orthagonal to the question
of why channels.

for example, if you have a couple of i/o threads and one mux,
the mux can wait for a message from one of the i/o threads
that might say
a) here's your data (8192 byte+overhead message), or
b) your data is here (sizeof pointer+overhead message)
