I'm sorry, but I can't understand this meaning.

1. Any code of CUPS doesn't use /dev/random. Only cert.c uses
   /dev/urandom instead of it.
2. I couldn't catch meanings of "300 bytes" and "timeout loop".
   cert.c gets 4 bytes from /dev/urandom in the straight procedure.
3. If /dev/urandom doesn't exist, time-based seed generator will be
   called.

Could you tell me more information? Do I miss something?

Thanks,
