rake resque:pool isn't respecting TERM_CHILD?

I think I'm seeing an issue where rake resque:pool doesn't honor the TERM_CHILD=1 flag. If I run resque-pool, it does work as expected.

Here is the output from rake resque:pool:

~/app $ TERM_CHILD=1 bundle exec rake resque:pool

resque-pool-manager[integrations][34935]: manager finished

Here is the output from resque-pool:

~/app $ TERM_CHILD=1 bundle exec resque-pool

I notice this line: resque-pool-manager[34858]: TERM_CHILD enabled, so will user 'term-graceful-and-wait' behaviour indicating that term child is enabled. Does the lack of this in the rake resque:pool mean what I think it does - that TERM_CHILD isn't respected?

Compare the rake resque:pool entry point with the resque-pool executable, focusing first on how TERM_CHILD is read and passed to the pool manager. Reproduce both commands with TERM_CHILD=1 and verify that the rake task selects the same term-graceful-and-wait behavior and emits the corresponding enabled message.
