Here's a new patch that incorporates some of these changes. Specifically:

- I've removed some of the assertions
- I've installed a custom allocator, as you suggested
- Reverted back to creating a temporary string and inserting that into the
buffer. Anything else just doesn't seem to work or seems way too complex.
- Introduced explicit encoding and decoding. I suspect that will lead to a
massive performance hit, but I haven't done any benchmarks yet.
- Added manual section and NEWS entry
