Yes, that's frustrating. I wish that we had a more reliable interface at
the notmuch library level. But I'm not entirely sure what would be the
best way to do this.

The emacs code does not use the notmuch library interface like your
python bindings do. Instead, it uses the notmuch command-line tool, (and
buffers up the text output by it). The support for asynchronous
operations in the emacs interface means that it's likely possible
someone could run into a similar problem:

	1. Start a search returning a *lot* of results

	2. When the first results come in, make some tag changes

	3. See if the original search aborts

I may have even had this happen to me before, but if I did I've never
actually noticed it. I don't know what a good answer might be for this
problem.
