in the past we have faced a couple of problems with corrupted system 
tables. this seems to be a version independent problem which occurs on 
hackers' from time to time.
i have checked a broken file and i have seen that the corrupted page has 
actually been zeroed out.

my question is: are there any options to implement something which makes 
system tables more robust? the problem is: the described error happens 
only once i an while and cannot be reproduced. maybe there is a way to 
add some more sanity checks before the page is actually written.

any suggestions?
best regards,
    hans
