> *Problem*
> Currently we always lock trash ID during during file create if "overwrite"
> flag is set to {{true}}. This is very pessimistic strategy leading to
> contention on trash. In lots cases there will be no existing file.
> *Solution*
> 1) Trash should be locked only if there is a clear evidence that old file
> exists.
> 2) If we didn't lock trash and found existing file - go to re-try loop. This
> is very unlikely case.
