Inconsistency when writing to StorageDict

[adrianespejo]

In [4]: class URCA(StorageDict):
   ...:     '''
   ...:     @TypeSpec <<int>,int>
   ...:     '''
   ...:     

In [5]: a=URCA('hola.ciao')

In [6]: for i in range(10):
   ...:     for j in range (10):
   ...:         a[i]=j
   ...:         

In [7]: a
Out[7]: {0: 8, 1: 6, 2: 8, 3: 8, 4: 8, 5: 9, 6: 9, 7: 9, 8: 9, 9: 9}

a should be {0: 9, 1: 9, 2: 9, 3: 9, 4: 9, 5: 9, 6: 9, 7: 9, 8: 9, 9: 9}

@cugni This is related to overriding the same value (a[i]). We use an asynchronous, parallel, writing strategy without timestamps. Therefore, we can't enforce "last write wins" and we should change the current implementation.

Actually, we need to change the write strategy to solve #122

[cugni]

relates to #234 and #233

Fixed by #233
