Googling for "Allocator race" yielded little of interest but I found
my way to Apple's 'File Manager Reference'

In my very limited experience (I'm not a developer)
the *sequence* and/or *timeliness* of 'responses from a file
system' (I use that expression loosely) may be critical to things such
as Finder transaction verification.

Returning to the start of this thread: if the context is imapfs
http://code.google.com/p/imapfs/
then I might question the general abilities of IMAPs server to succeed
with all requirements in good time.

For example: if/when
._atira.png
is removed, does the underlying IMAP service allow the File Manager to
know this in good time?

My guess: for as long as File Manager sees
._atira.png
then Finder will consider that the copy has not completed.

Good luck
