Bug report: Too many messages fetched at once with maxage

[Ivan Semin]

I am having problems with maxage too (not sure it's the same bug though).
I have a gmail account which is 90% full. I am doing a one-way sync
(readonly=1) from gmail to my local backup server. Now I want to
delete all messages that are >3 months old from gmail, but I don't
want them deleted from the local box. So I set maxage=90 and run the
sync again. I did NOT delete any messages from gmail yet! That's what
offlineimap 6.3.4-rc2 is doing:
