Description of problem:
The SIGPIPE signal is set to be ignored in rhnsd.c via syscall:
signal (SIGPIPE, SIG_IGN);

Due to this, actions (commands) scheduled to be executed via RHN, when
executed using rhn_check, also inheret an ignored SIGPIPE

This causes problems with certain utilities like cron, which when
restarted, pass this Ignored SIGPIPE further down causing problems like:

zcat: stdout: Broken pipe
(while running makewhatis.cron)

Refer Bugzilla #64836

Possibly also impacts up2date-4.2.57-2 from RHEL 3 Update 4.

Version-Release number of selected component (if applicable):
up2date-4.2.38-1

How reproducible:
Always

Steps to Reproduce:
Run the following via Remote Command -> Script Window

#!/bin/sh
exec 1>/tmp/test
echo "Sending SIGPIPE to Self (Pid $$)"
kill -s SIGPIPE $$
echo "SIGPIPE Ignored"


Actual Results:  (Executed via rhnsd)

# cat /tmp/test
Sending SIGPIPE to Self (Pid 7069)
SIGPIPE Ignored

Expected Results:  (Running Directly via Shell)

#./test.sh
Sending SIGPIPE to Self (Pid 7115)
Broken pipe
