mux tests memory footprint

[coot]

Some of the mux tests are quite expensive to run:

• mux send receive bidir
• mux send recieve
• miniprotocols Pipe
• miniprotocols Queue

mux send receive bidir

cabal run network-mux:test -- --quickcheck-replay=0 +RTS -t -RTS -p '/mux send receive bidir/'
mux
  Mux
    mux send receive bidir: OK (47.13s)
      +++ OK, passed 100 tests.

All 1 tests passed (47.13s)

d), 4.698 GC (4.709 elapsed) :ghc>>

mux send receive

Note as bad as the former (~80MB).

cabal run network-mux:test -- --quickcheck-replay=0 +RTS -t -RTS -p '$3 == "mux send receive"'   
mux
  Mux
    mux send receive: OK (24.55s)
      +++ OK, passed 100 tests.

All 1 tests passed (24.55s)

miniprotocols Pipe

cabal run network-mux:test -- --quickcheck-replay=0 +RTS -t -RTS -p '/miniprotocols Pipe/'
mux
  Mux
    2 miniprotocols Pipe: OK (6.92s)
      +++ OK, passed 50 tests.

miniprotocols Queue

cabal run network-mux:test -- --quickcheck-replay=0 +RTS -t -RTS -p '/miniprotocols Queue/'                                             
mux
  Mux
    2 miniprotocols Queue: OK (10.01s)

Other tests

Other tests seem fine:

cabal run network-mux:test -- --quickcheck-replay=0 +RTS -t -RTS -p '!/miniprotocols Pipe/ && !/mux send receive/ && !/miniprotocols Queue/' 
...
