Exception is never raised in fm_dispatch due to self-kill

[berland]

The os.killpg kills the fm_dispatch process such that the exception e is never raised. If there is a bug in fm_dispatch that triggers an exception, it will not be printed to the terminal. Running fm_dispatch in the runpath only gives you the output Terminated.
