1) Allocate css_style bytecode in 16 byte chunks
2) Cache unused css_style objects with chunks of size 16, 32, 48, and 64 bytes
The above should reduce heap churn somewhat.
Further improvements are possible:
1) Make the property parsers write the parsed values direct into the output
bytecode, instead of into a temporary object which is then merged into
the output.
2) Perform similar caching for css_rule and selector objects.
3) Shrink-wrap finalised output styles rather than leaving them oversized.
4) Perform measurement to determine the optimal chunk sizes (power-of-2 makes
maths simple and 16 is plucked from thin air) and cache bucket count/sizes.
