Nope. There isn't.
You often see this sort of problem in web server caches, where you have
a gazillion processes all trying to create variants on the same
directory structures. This may fail because two processes tries to
create /var/tmp/cache/foo/bar/zot at the same time, for instance.
Trying to unwind this in a general fashion is impossible, and must be
left to a higher level to determine what to do.
