Oh. "Entropy source draining" is not a real thing. There used to be bizarre behavior related to /dev/random (not urandom), but this has been gone for ages. And even the non-getrandom Linux fallback code uses /dev/urandom before /dev/random. So not even on old kernels is this an issue. You can keep generating random numbers forever without worrying about running out of juice or irritating other processes.
Thank you. This probably seals the deal. I'll prepare a patch removing the direct use of the hardware instructions in the coming days.
Cool. I've got an account on the Qt Gerrit (I think, anyway; it's been some years), in case it's useful to CC me.
