Description

We were trying the new config_loader option by passing a lambda, but we see that the Resident Set Size (RSS) of the resque-pool doubles within an hour. When we start the resque-pool, the size was around 500MB but within an hour, the size is above 1G. Without using the config_loader, the RSS remains stable (around the initial size). It seems like whatever object that was created/used within the lambda block is not being GCed.

Research direction

Start by reproducing the resque-pool RSS growth with a lambda passed through config_loader, comparing it with a run without that option. Then trace how config_loader retains or invokes the lambda and use memory measurements to identify the retained object; done means RSS remains stable under the reported configuration.
