unable to terminate certain processes with keyboard interrupt (ctrl+c)

[yqiang]

OS X 10.8.3
fish 2.0.0

From time to time fish doesn't return command back to shell after exiting an application.

Repro steps:

• Run fish_config
• Hit ctrl+c to exit the program

Expected behavior:

• User is returned to the shell

Actual behavior

• Shell seems to be stuck trying to exit. The last output is "KeyboardInterrupt" from the python script.

Sample from activity monitor:

FWIW after waiting a while and hitting ctrl+d it returned me back to the shell. Hitting ctrl+d again gave the following error:

It looks like this is caused by the oh-my-fish bundle. I'm not able to repro after removing it.
