External entropy pool for random number generator
In the attachment patch which allow to use external entropy pool for
Kernel::rand.
When entropy pool present and you run Kernel::rand it reads 4(should
be more?) bytes from pool and use this value as random seed. When pool
ends(EOF reached) it sets to nil.
It can be useful for cryptography or for testing. For example:
srand(File.open("/dev/random")) # use system entropy pool
rand
srand # use standart ruby's generator
