Comment (by pento):

 [attachment:28786.11.diff] now also sanity checks array/object keys.

 And because we all like things that go faster, unwinding unnecessary
 recursion gives us a bit of a boost when we need to sanity check the data.

 {{{
 $ php json_test.php
 json_encode: 0.055270910263062
 wp_json_encode overhead: 0.058070182800293
 Best case wp_json_encode: 0.98551392555237
 Worst case wp_json_encode: 4.3197019100189
 }}}
