Thanks for the pointer, I've pinged the issue offering help with the
bindings and had a look through the existing things they discussed.

One thing that they encountered and don't yet understand is that they
reported issues with leaking filedescriptors.  They used the bindings in
a way where I expect it to only call notmuch_database_destroy() when
they are done with it.  From reading notmuch.h I think that's correct
and there's no need to call notmuch_database_close() first.  Yet someone
reported that explicitly calling close helped.  Is the assumption I made
of only calling destroy correct?

Cheers,
Floris
