pseudocode
do
RandomFileName = SomeRandomFileNameCreator(basename)
if not exist RandomFileName
exit
end if
loop
There's still a very very small chance of a race condition, but unless
you are going to use a semaphore supplied by the OS or Server, that's a
cross you have to bear. But it's a very tiny race condition and I've
never found it to be a problem in production code, especially if the
random number is large and is properly reseeded.
