pndev shell does not exit after killing ember server with ctrl-c

[christophermlne]

Steps to reproduce

• from within the es-student (or es-certification) folder, run pndev start
• try to quick the ember server after it has started with ctrl-c

Actual

• shell hangs on message 'Cleaning up...'

Expected

• shell should exit cleanly

so I did a bunch of research

it is not hanging up and it does exit cleanly

but because of how processes work in UNIX
when you send CTRL+C (which sends the SIGTERM signal) pndev is killed

that in turns kills ember s or forego in rails

but those processes have cleanup routines that run after pndev has already exited because they appear to happen in separate processes that are forked.

Unless we're willing to do a TON of work on signal handling this will be hard to fix

I propose that you just press ENTER once you CTRL+C a pndev start and be ok w/it for now :)
