Non-concurrent API compatible with webworkers for environments where webworkers are unavailable
Works as drop-in replacement for @substack's webworkify, instead of:
w = require('webworkify')(require('./worker.js'));
w = require('unworkify')(require('./worker.js'));
Compatible with NodeJS and browserify. Warning: incomplete and possibly buggy API implementation
webworkify in the browser and
unworkify on servers (based on the webworkify example).
