It doesn't say much about sizes you can request and what the
result of that would be.  The getentropy() replacement seems to
suggest 256 isn't something you want to do (when GRND_RANDOM is
not set?).  random(4) says not to use > 256 bit (32 byte).

Shouldn't it return a ssize_t instead of an int?  I see it's
limited to INT_MAX, but it seems in the code to return a ssize_t
but the manpage says int.
