Doesn't the new SYNC_AFTER_WRITE flag address this issue? Here is the doc
# This flag causes Mailman to fsync() its data files after writing and
# flushing its contents. While this ensures the data is written to disk,
# avoiding data loss, it may be a performance killer. Note that this flag
# affects both message pickles and MailList config.pck files.
