Comment (by robgjansen):

 Interesting, I've been running Tor this way since Shadow was created, and
 I haven't had too many issues.

 Of course I can handle this from within Shadow by adding a constant offset
 to the emulated time. Regardless, IMO, I think it is dangerous to accept
 negative inputs to a function that assumes they are not, and without
 assertions. Maybe there is a use case here? Otherwise, why not remove the
 function entirely and force calling `crypto_rand_uint64` directly.

 Anyway, feel free to ignore me and close this ticket, and I'll make the
 changes to Shadow to prevent the problem from happening.
