[PATCH v3 1/3] eloop: dump a trace when exiting due to SIGALRM

[Benjamin Berg]

From: Benjamin Berg <benjamin.berg at intel.com>

We configure a SIGALRM when receiving a signal to exit. If this SIGALRM
is fired, then the process did not properly exit. When this happens,
dump a trace to help with debugging.
