    pluto: prevent curl from sending confusing signals crashing pluto (lsbz#128)
    
    This would manifest itself when you need a CRL to bring up the tunnel,
    but the CRL fetch location is on the other end of the tunnel (or otherwise
    resolving fails)

    	libcurl built without an asynchronous resolver library uses
    	alarm() to time out DNS lookups. When a timeout occurs,
    	this causes libcurl to jump from the signal handler back
    	into the library with a sigsetjmp, which effectively
    	causes libcurl to continue running within the signal
    	handler. This is non-portable and could cause problems on
    	some platforms. A discussion on the problem is available at
    	http://curl.haxx.se/mail/lib-2008-09/0197.html
    
    	Also, alarm() provides timeout resolution only to the nearest
    	second. alarm ought to be replaced by setitimer on systems that
    	support it.
    
    Note this seems to have happened in Fedora, but not yet in RHEL6
