+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.

The kill dejagnu 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 'kill with SIGUSR1' failures on the autobuilder, particularly on qemuarm64. Skip only the three signal-based test cases while keeping the nine reliable argument-parsing tests (signal name/number conversion, etc.).
