correction to what i just wrote: the mailbox file i was inc'ing from
had a whole lot more than 100 messages in it. the inc stopped at 100,
with the BUG message i quoted below. i just did another inc from there,
and it pulled in another 319 messages.

no sure whether this is directly related the to the following thread,
but i want to pass it on before i lose the text. i just did an inc of
100 messages into an empty folder. i'm running a CVS snapshot from
around the time of the bad RC2 release. it has the simpler of the fixes
being discussed applied to it. i just got the following message:
inc: BUG: called folder_realloc with lo (1) > mp->lowmsg (0)
i don't have time right now to look into this -- but i can provide more
details about my code base if anyone needs them...
