> Current implementation of WASB does not correctly handle multiple threads/clients calling
delete on the same file. The expected behavior in such scenarios is only one of the thread
should delete the file and return true, while all other threads should receive false. However
in the current implementation even though only one thread deletes the file, multiple clients
incorrectly get "true" as the return from delete() call..
