>Description:
	MoziillaFirebird invokes netstat(1) with file descriptor 0 closed.
>How-To-Repeat:
	dmesg output has something like below.

Jan 15 09:43:25 starfruit /netbsd: set{u,g}id pid 10045 (netstat) was invoked by uid 1001 ppid 9877 (MozillaFirebird-) with fd 0 closed

>Fix:
	1. open /dev/null to fill file descriptor 0.
	2. i guess the reason to invoke netstat(1) is to get random number.
	   it is better to teach MozillaFirebird to use /dev/urandom.
