cyclictest can be run from other tools such as rteval
in order to get current status on long runs, SIGUSR1 is sent to
cyclictest and caught by function sighand()
This creates difficulties for rteval when parsing cyclictest output, so
change the output to stderr.
Note, a RFC was sent out on Apr.15 2014 entitled
"RFC: SIGUSR1 to stderr"
to: RT <linux-rt-users@xxxxxxxxxxxxxxx>

Thomas Gleixner <tglx@xxxxxxxxxxxxx>,

Since I didn't receive any replies, I'm assumin there are no objections
