[Dovecot] Zero-sized Maildir files (and alledged index corruption) on over-quota

I don't know whether the NFS server behaves that way (I would have to try out), but how would dovecot's LDA behave if, for a small message, upon the write (to tmp) the write() succeeds and the close() (which would actually try to flush the buffered data to disc) fails?

Would you consider "upon close()" as "way too late"?
