Yes, this will probably take a while until this shows up in a release version 
of OpenBSD. But if this is not reverted then it will probably be a good idea 
to have check for this in 3.2 ready so it will just work in the next release 
of OpenBSD.

There will be srand()/rand() on OpenBSD. It's just that srand() will be 
ignored and rand() will return really random numbers if there has not been a 
call to srand_deterministic() before, which will make rand() return the same 
numbers as on other platforms.

The idea behind this API in OpenBSD is: if you are looking for the pseudo 
numbers you need to call srand_deterministic(), i.e. you must explicitely 
state that you want the not really random random numbers. Everyone else will 
get real random.
