The following is a demonstration of the sigdist.d script.
Here we run sigdist.d, and in another window we kill -9 a sleep process,
# ./sigdist.d
Tracing... Hit Ctrl-C to end.
^C
SENDER RECIPIENT SIG COUNT
sched dtrace 2 1
sched bash 18 1
bash sleep 9 1
sched Xorg 14 55
We can see the signal sent from bash to sleep. We can also see that Xorg
has recieved 55 signal 14s. a "man -s3head signal" may help explain what
signal 14 is (alarm clock).
