OCaml's buffered 'in_channel' has a 64k buffer, so using it to read a few bytes from /dev/urandom removes a lot of the system's entropy (for example /proc/sys/kernel/random/entropy_avail goes from ~3000 to 128). This patch was originally by Edwin Török for builder.ml. I generalized it because there are two other places where we did over-sized reads from /dev/urandom.
