[OSX only] newrelic make workers reaping indefinitely

[jobwat]

This may be probably related to issue #25, as a comment from there just lead me to realize newrelic was probably the cause...

The issue: resque-pool gets crazy after a little while...

^Cresque-pool-manager[webapp][63824]: INT: immediate shutdown (graceful worker shutdown)
resque-pool-manager[webapp][63824]: manager finished

that's not always been the case, it's working like a charm on linux servers, and the problem seems to have disappeared since I've removed newrelic instructions

I have no idea how to debug from there :|

[jobwat]

Confirmed: it's newrelic gem

Even if you remove all related hooks, the gem will somehow mess with resque-pool...

[jobwat]

I've commented it out in config/newrelic.yml and my world is back to bright :)

Under the development: section:

  # New Relic gem mess up with resque-pool under OSX.. - https://github.com/nevans/resque-pool/issues/70
