@nick: I used this function in one of my cgi scripts, to be sure the data saved to file even there is a concurrency (I know it is a soooo rare situation if server is not heavily loaded)
safe-save: func [file [file!] data] [
loop 3 [
if attempt [write/append file data wait 0.3 true] [break/return true]
if none? safe-save %file data [error-saving-data]
might be useful for someone.

I can use that :)

I can vouch for this approach.
We use very similar code on all the CGIs at REBOL.org. Deploying it reduced very rare (perhaps once a year) write failures to (so far, in several years) none at all.
We have similar read-safe and delete-safe functions too.

Really? I'm glad I'm on the right way :)
