fix(sew): limit go routine spawn for activating delegation #8

	# Adapted from https://github.com/marketplace/actions/backporting
	#
	# Usage:
	# - Let's say you want to backport a pull request on a branch named `production`.
	# - Then label it with `backport production`.
	# - That's it! When the pull request gets merged, it will be backported to
	# the `production` branch. If the pull request cannot be backported, a comment
	# explaining why will automatically be posted.
	#
	# Note: multiple backport labels can be added. For example, if a pull request
	# has the labels `backport staging` and `backport production` it will be
	# backported to both branches: `staging` and `production`.
