[PATCH] Print stack for lazy workers

[Camilo Lopez]

This patch attemps at making the debugging of lazy workers easier by making sure
unicorn prints a stack trace to STDERR.

The patch does 2 things

1. It kills lazy workers with TERM first and then attempts a KILL
2. Prints the stack trace on every kill signal

Camilo Lopez (1):
Kill lazy workers with TERM before KILL
