+both requests and responses.  The parser is designed to be used in
+high-performance HTTP applications.  It does not make any syscalls nor
+allocations, it does not buffer data, it can be interrupted at anytime.
+Depending on your architecture, it only requires about 40 bytes of data per
+message stream (in a web server that is per connection).")
