… anyways The most expensive call at the moment is repo.get_changed_files, which does down the drain if: - another default_fn overrides the value - an explicit override is given when creating the `Parameters` With this change, the default function can return a function as a value, which is not evaluated unless necessary. Fixes taskcluster#616

…ing. r=taskgraph-reviewers,jcristau Loading the tasks for the toolchain kind doesn't trigger the optimization passes that use files_changed, so we can just override the parameter to avoid the defaults expensively trying to determine what they are. We also change the default parameters in gecko_taskgraph to apply the same change as taskcluster/taskgraph#624. Differential Revision: https://phabricator.services.mozilla.com/D234628
