node.js when opening multiple fifos

fifo_bug.js

// Opening fifos, which nobody is reading from causes strange behaviour and has
// side effects on opening network connections to localhost

// Bug #1
// ------
// run with "node fifo_bug.js 1"
// The client will connect but process.exit(0) has will not terminate the process
// then do "cat fifos/fifo0"
// this will cause the process to exit
// Note: this does not happen with 0.6 or 0.8


// Bug #2
// ------
// run with "node fifo_bug.js 4"
// The client will never connect to "localhost"
// Note: this happens in node 0.6, 0.8, 0.10 and 0.11
