Description

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..
