 If an external command like DelegationSignerSubmitCommand or NotifyCommand
 fails in a way that goes unnoticed for popen, currently OpenDNSSEC can't
 detect it.

 Attached you will find a C code that tries to popen a perl script, which
 contains a syntax error. Neither popen nor fprintf detect the error, only
 at pclose a SIGPIPE signal is sent. This means the failure goes under the
 radar.
