Hmm.. Starting from a totally empty user, not even an inbox in sight, and
using that 1 imapd process which grew to 37Mb to CREATE and APPEND repeatedly,

Oh!

# du -ck . (Inside /var/spool/user/userid)
514     ./Sent/2003/08-Aug
...
38104   .
38104   total

  PID USERNAME PRI NICE   SIZE   RES STATE      TIME   WCPU    CPU COMMAND
19526 cyrus      2    0    35M   37M select     0:10  0.93%  0.93% imapd
(I killed it just after)

Now, why would the total quantity of data written to disk in that session
magically tally with the process' size.. I'd better try again in case this
is coincidence.. That figure obviously includes not only the message
files, but also cyrus.index & cyrus.cache for each mailbox, the biggest
being

-rw-------  1 cyrus  mail  409268 Sep 24 11:55 ./Sent/2003/03-Mar/cyrus.cache

which isn't much..

Cheers,
