Fixes an example for the job queue constructor (which now requires a second positional argument, intended to be a Queue() object)
Also addresses #1305 (comment) . We'll now only set exit status if it's a process and do nothing if it's a thread.
[#1305] Add queue for try_using examples
[#1305] Only alter the exit_code if job is a Process
- Addresses this comment on issue:
- no status code to set for Threads anyway
- only processes used in fabric internals
Changelog, fixes #1305, fixes #1313
