Instance Method Details

#gc_stress(interval = 1) ⇒ Object

For use in development only, of no practical use in production code. This method causes Ruby’s garbage collection to run (roughly) at interval interval (seconds) - the default is 1, i.e. every second. This should help ferret out bugs in memory management more quickly.
