From 1958962be33d78f6360898e65628944a17ee1614 Mon Sep 17 00:00:00 2001 From: Boris Zbarsky Date: Tue, 11 Jul 2023 13:56:44 -0400 Subject: [PATCH] Increase our "waiting for subscription to time out" timer slack. (#27870) 100ms is not enough: we have tests losing the timeslice for that long, and then we break out of our "waiting for timeout" loop before we process the firing of the timeout timer.
