Carl Worth f2bcc256fb TODO: More notes on archive-thread and race conditions.
Interstingly, it's our simple "notmuch" client that's going to be the
most difficult to fix. There's just not as much information preserved
in the textual representation from "notmuch search" as there is in the
objects returned from notmuch_query_search_threads.

Write a "notmuch tag" command to add/remove tags from messages
matching a search query.
Write a "notmuch show" that displays a single thread.
Fix to use the *last* Message-ID header if multiple such headers are
encountered, (I noticed this is one thing that kept me from seeing the
same message-ID values as sup).
Think about this race condition:
A client executes "notmuch search"
Then executes "notmuch show" on a thread
While user is reading, new mail is added to database for the thread
Client asks for the thread to be archived.
The bug here is that email that was never read will be
archived. That's bad. The fix for the above is for the client to
archive the individual messages already retrieved and shown, not
the thread. (And in fact, we don't even have functions for removing
tags on threads.)
But this one is harder to fix:
A client executes "notmuch search"
While user is reading, new mail is added to database for the thread
Client asks for a thread to be archived.
To support this operation, (archiving a thread without even seeing
the individual messages), we might need to provide a command to
archive a thread as a whole. The problem is actually easy to fix
for a persistent client. It can onto the originally retrieved
thread objects which can hold onto the originally retrieved
messages. So archiving those thread objects, (and not newly created
thread objects), will be safe.
It's harder to fix the non-persistent "notmuch" client. One
approach is to simply tell the user to not run "notmuch new"
between reading the results of "notmuch search" and executing
"notmuch archive-thread" (or whatever we name it).
