Summary: In `Unix/Process.inc`, we seed a random number generator from `/dev/urandom` if possible, but if not, we're happy to fall back to ordinary pseudorandom strategies, like the current time and PID. The corresponding function on Windows calls `CryptGenRandom`, but it //doesn't// have a fallback if that strategy fails. But `CryptGenRandom` //can// fail, if a cryptography provider isn't properly initialized, or occasionally (by our observation) simply intermittently. If it's reasonable on Unix to implement traditional pseudorandom-number seeding as a fallback, then it's surely reasonable to do the same on Windows. So this patch adds a last-ditch use of ordinary rand(), using much the same strategy as the Unix fallback code.
