Assume a user's secret key is stolen and he is known to use one of
200,000 English words as his password. The system uses a 8-bit salt.
The amount of combinations is 256*200000 = 51200000.

 If attacker chacks one hash per second and has 64-core beowulf
cluster it will require 9 days to check all possible combinations.
That's not so much, imo.
Also, processors are cheap these days one guy [1] has build 96-core
machine (for unknown price).
