Improve slurp performance by using native Java StringWriter and jio/copy
Description
Instead of copying each character from InputReader to StringBuffer.
Performance improvement:
Approach: Use StringWriter and jio/copy vs character by character copy. Results from the current patch see a 4-5x perf boost after the jit warms up, with purely in-memory streams (ByteArrayInputStream over a 6MB string).

Is this blocked on a new perf comparison? Should I post one?

This is with an SSD, no idea what the numbers would look like with a spinny disk.
