+Subject: [PATCH] drd/tests/swapcontext: Add SIGALRM handler to avoid
+ stacktrace
+
+During testing for oe-core build on QEMU,
+SIGALRM can trigger during nanosleep.
+This results a different stderr output than expected.
+
+```
+==277== Process terminating with default action of signal 14 (SIGALRM)
+==277==    at 0x36C74C3943: clock_nanosleep@@GLIBC_2.17 (clock_nanosleep.c:43)
+==277==    by 0x36C74C8726: nanosleep (nanosleep.c:25)
+```
+
+This stacktrace printing will not occur
+if we add a handler that simply exits.
