So what if we instead modified the top level binary ("notmuch") to:
* add an option to specify that commands are to be processed from stdin
(--batch)
* when in batch mode the db is opened once at the beginning and locked
* commands are processed from stdin in the exact same form they are
specified on the command line ("tag +foo -- from:bar", "search
tag:foo", etc.).
* db is closed when EOF is reached.
That seems like it would be a generally much cleaner interface, and much
more flexible.
