+Subject: [PATCH] testsuite: skip signal-based kill tests
+
+The kill tests that send signals to a pipeproc helper (SIGUSR1, SIGUSR2,
+and queued signal) have a race condition where test_process can exit or
+become unavailable before the expect script reads its output, resulting
+in "spawn id not open" errors. This causes intermittent failures on
+loaded systems, particularly under QEMU emulation.
+
+Skip these tests with 'untested' while keeping the non-signal kill tests
+(argument parsing, signal name/number conversion) which are reliable.

+Upstream-Status: Inappropriate [upstream ticket: https://gitlab.com/procps-ng/procps/-/issues/423]
