I *think* nonblocking_urandom_noraise.patch will solve the 90+ second start up without affecting os.urandom which should solve the first one (once the already applied patch gets reverted), but I'm afraid I don't know C well enough to meaningfully review that for accuracy.

None of the current patches solve the second without invalidating the first, but it would be, I believe, an additional patch ontop of nonblocking_urandom_noraise.patch.

The third is already the case.
