Public bug reported:

When user sends SIGKILL (kill -9) or SIGTERM (kill -15) signal to nova-
comupte parent process then parent process terminates immediately but
child process keeps running forever and keeps processing the requests
received from rabbitmq.

Steps to reproduce:

1. Identify running processes of nova-compute using "ps aux | grep nova-compute'
2. Send kill or terminate signal to parent process.
   $ kill -9 <nova-compute-parent-process-id> or kill -15 <nova-compute-parent-process-id>
3. Verify parent process is killed using "ps aux | grep nova-compute'

** Affects: nova
     Importance: Undecided
         Status: New

** Summary changed:

- nova compute child process remains orphan after sending kill or interrupt signal to parent process
+ nova compute child process remains orphan after sending sigkill or sigterm signal to parent process

** Description changed:

- When user sends SIGKILL (kill -9) or SIGINT (kill -15) signal to nova-
+ When user sends SIGKILL (kill -9) or SIGTERM (kill -15) signal to nova-
  comupte parent process then parent process terminates immediately but
  child process keeps running forever and keeps processing the requests
  received from rabbitmq.
  
  Steps to reproduce:
  
  1. Identify running processes of nova-compute using "ps aux | grep nova-compute'
  2. Send kill or terminate signal to parent process.
-    $ kill -9 <nova-compute-parent-process-id> or kill -15 <nova-compute-parent-process-id>
