Useful error messaging when out of memory

[GoogleCodeExporter]

If I exceed the memory allocated to Redis, I (expectedly) get the following
error:

$ ./redis_test.py 
Traceback (most recent call last):
  File "./redis_test.py", line 8, in <module>
    r.set(1,'0123456789')
  File "/usr/lib/pymodules/python2.6/redis.py", line 137, in set
    return self.get_response()
  File "/usr/lib/pymodules/python2.6/redis.py", line 975, in get_response
    raise ResponseError(data[5:] if data[:5] == '-ERR ' else data[1:])
redis.ResponseError: command not allowed when used memory > 'maxmemory'
rlowe@hp1k:~/scratch$ 

It would be useful to me to have the following two data points in the error
output:

- How many bytes were needed to complete the operation
- How much memory was allocated to Redis at the time (redis.conf is not
necessarily authoritative)

"how many memory where needed" is a low level information that I think should 
not be exported, instead, how much memory was allocated can be requested via 
INFO. Also using "CONFIG GET maxmemory" it is possible to access the current 
configuration.
