Fixes haskell#181, the documentation seems to have been misread, the argument to `_pipe` is the number of bytes to reserve for pipe communications, not the number of pipes to create. This ended up making pipes that can only send 2 bytes at a time. Instead use 8k which is the size of the internal Buffers in `Base` which back `I/O` calls.

Fixes #181, the documentation seems to have been misread, the argument to
_pipeis the number of bytes to reserve for pipe communications, not the number of pipes to create. This ended up making pipes that can only send 2 bytes at a time.The pipes are created in blocking mode, so any write of larger than 2 bytes block and no read returns more than 2 bytes..
