Log Message:
Backport fix for CVE-2006-0353 from lsh2:

"unix_random.c in lshd for lsh 2.0.1 leaks file descriptors related
 to the randomness generator, which allows local users to cause a denial
 of service by truncating the seed file, which prevents the server from
 starting, or obtain sensitive seed information that could be used to
 crack keys."
