>Description:
1. If a long write to /dev/random is interrupted by a signal, it may proceed to sleep on the entropy source lock instead of returning promptly.
2. If a write to /dev/random is interrupted by a signal while sleeping on the entropy source lock, it may fail to report EINTR.
3. If `sysctl -w kern.entropy.consolidate=1' is interrupted by a signal, it may fail to report EINTR.
4. If ioctl(RNDCTL) is interrupted by a signal, it may fail to report EINTR.
>How-To-Repeat:
randomly randomize randomness and signals

Yes, please!
