> couch_config:delete/2 is implemented as

>     set(Section, Key, "").
> I think that's misleading -- a key with an empty value is not the same as no key at all.  Consider the case of an update_notification process.  To me, deleting that key should just send an EOF to the process.  Instead Couch sends the EOF and then tries to spawn an os_process to execute "".  The end result is the same, but a few things crash along the way.
