From c37a6e8e40e50e96e4e8a5414ce702f0156fde77 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Bernon?= Date: Wed, 10 Nov 2021 10:26:45 +0100 Subject: [PATCH] server: Wait for process exit more often and using increasing delay. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of waiting for 1s before considering it dead, when most of the time the process dies quickly, delaying desktop or wineserver shutdown.
