I just tried testing this myself in a mailbox with around 10000 mails. I
tried deleting everything, I tried deleting messages from here and there
(sorted the mails based on size and deleted half of them), etc. At no
point did the process's size grow more than a few hundred kilobytes..

So, how large is the mailbox you're deleting messages from (ie. how many
messages do you leave there)? With mbox or maildir? What client are you
using to delete them? Are you deleting the messages in sequential order?
