crypto.pbkdf2 with an keylen too long crashes in a segfalt
in node 4.1.2 and latter calling
crypto.pbkdf2('password','salt', 1, 4073741824, function(err, resp){console.log(err, resp)});
causes node to crash with the message
Segmentation fault: 11
node 4.1.1 and earlier throw a TypeError: Bad key length
crypto-browserify/pbkdf2#22
I suspect this commit 4c8d96bc is to blame
