cordova emulate android doesn't exit

Cordova CLI 3.2.0-0.4.0
Android Platform 3.2.0

condition: no android emulator running

cordova create hello
cd hello
cordova platform add android
cordova emulate

Results:
emulator starts
app gets installed
app starts fine
But command prompt never exits.

Expected results:
cordova command to exit

This affects other projects like grunt-cordovacli and generator-cordovacli because other commands are expected to run after "cordova emulate"
