Detailed Description

Proxy environment buffer.

The first 64 bytes of the environment structure are a scratch area. The Root proxies put a collection iterator there, but we instead lay it out like this.

This is slightly different in newer versions of root. Rather than having the 64-byte buffer, Environ takes a template argument giving the payload.
