I guess my idea above was that mbox_snarf would:

1) Do nothing special when opening the mailbox (unlike now), except add
hooks to sync_init and mailbox_close.

2) when mbox_snarf_sync_init() is called the first time:
 - find mbox_snarf namespace
 - open INBOX from that namespace and keep it open
 - goto 3)

3) every time mbox_snarf_sync_init() is called:
 - call mbox_snarf()

4) on mailbox_close() close the snarf mailbox

Maybe the above helps? That Plugins wiki page probably won't help you
much, since the current mbox_snarf already sets up the plugin stuff
correctly. "Overriding methods" is probably the only important part
there. The other Design/* pages could be more helpful.
