example reproducer code tarball

actually, even a simple C program (attached) becomes slow
when just linking against libcrypto,
without actually calling any lib function.

and strace -ttt shows the most time being spent again
between the 4th and 5th time /dev/urandom is opened

that is the one getting 256 bytes of randomness while the others get less
