use nextTick() instead of setImmediate() to schedule microtasks with node 0.10. Later versions of nodes are not affected as they were already using nextTick(). Note that using nextTick() might trigger a depreciation warning on 0.10 as described at https://github.com/cujojs/when/issues/410. The reason why nextTick() is preferred is that is setImmediate() would schedule a macrotask instead of a microtask and might result in a different scheduling. If needed you can revert to the former behavior as follow:
var Promise = require(‘es6-promise’).Promise; Promise._setScheduler(setImmediate);
