From 53bab198d93153f0123cb806ebb2b5c9ebbe8dc7 Mon Sep 17 00:00:00 2001 From: "Bryan C. Mills" Date: Fri, 5 Nov 2021 10:11:11 -0400 Subject: [PATCH] runtime: skip TestNoShrinkStackWhileParking on netbsd/arm64 This test appears to deadlock frequently on the only netbsd-arm64 builder we have (netbsd-arm64-bsiegert). Skip the test to provide more useful test coverage for other failures.
