Thanks for all the excellent suggestions. Right now I'm using filenames of the format <unix time>.<pid>.<counter>. I'm opening the files in a loop with O_CREAT and O_EXCL and if the initial open fails I increment the counter and keep trying until it works. I think that will be more than adequate for my needs.
