Sudden disk space usage peaks?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I just noticed -- while Zoe was consuming 100% of my CPU for a few
moments -- that free space on the partition where Zoe has its data store
went down to 40 MByte (from ~140 MByte) lasted there for a second or
two, and then came up again to the usual 140 MByte.

This is of particular interest for me because I already had the
situation that free space went down to zero (~70 MByte or so free
before) while Sylpheed, my mail programme, was fetching mails from Zoe,
which unfortunately caused Sylpheed to loose its UIDL-file (so it would
fetch all the mails again). =20

While the problem with sylpheed could probably be solved by improving
its handling of the (here quite precious hehe) UIDL-file, I'm still
interested in whether these peaks are expected and whether there's a
recommendation on how much temporary space one should keep around for
Zoe.

About my setup:  OS is Linux, Zoe and all the data is stored on a
partition exclusively used by my user, since the partition is mirrored
(on block level via RAID 1) and encrypted.  The partition uses ReiserFS.
(Hmm it might also be a correlation between Zoe, the encrypted disk
(which needs CPU to do en-/decryption on writes/reads) and some special
behaviour of ReiserFS, which causes somewhat delayed freeing of freed
space...)
