[REBOL] Re: Concurrent access to data file

Hi,
I don't have currently enough free time to read whole your email, but I would
like to suggest you to use semaphore like solution:
sem: open/new %semaphore.sem
->> error? try [delete %semaphore.sem]
== true
You can't delete your semaphore file while OS holds lock on it .... but be
carefull and don't open several instances of 'sem ...
The advantage here is - even if your app crashes, the solution will work,
because OS will free lock it holds upon the file and rebol will succesfully
delete it ... or so I think :-)
Hope this helps,
Cheers,
