"""Infrastructure for server-side request handlers.

Interesting module attributes:

* The request_handlers registry maps verb names to SmartServerRequest
22
* The jail_info threading.local() object is used to prevent accidental
23
opening of BzrDirs outside of the backing transport, or any other

transports placed in jail_info.transports. The jail_info is reset on

every call into a request handler (which can happen an arbitrary number

of times during a request).
