Problem with TSVNCache when file is deleted

Dear List,

I have a somewhat strange IDE. When saving, it writes to a temporary
file, then deletes the file, then recreates it from the temp-file
apparently by copying. Unfortunately, this mode of operation does not
work well with TSVNCache, at least if the file in question is large
(10 MB in my case). If Overlay Icons are enabled, TSVNCache opens the
to be deleted file and prohibits creating the new file. To my big
disappointment, the IDE deletes the temp-file and shows "Cannot create
file". Using "Save as" I can recreate the file.

Using sysinternal's File Monitor I have verified, that the file is not
written to by the IDE, ie. before I press save.

Why does TSVNCache begin to crawl in the first place?

Can TSVNCaches behaviour be changed, so that it doesn't lock (to be) deleted
files? Or that it is interrupted, if a delete is issued?

Is there a way to make windows block on the create?

Yes, I had the virus scanner (TrendMicro, which has no track record of
problems) in mind but was astonished to see TSVNCache having the file
open. I included the directory and excluded nothing in File Monitor's
filter dialog. The only other thing I see is Explorer querying the
directory.

Thanks in advance,

Jens

P.S.: I hope File Monitor output will be readable.

as you can see CLOSE, then CREATE).
