This is just my IMHO: headers are small and the probability that serious 
error appear there is lower that the probability of error on data. So it 
seems we may reduce crc strength for them.

In case of data - I just not sure if it is correct to use weaker 
algorithm... 
If somebody compitent may soundly explain why we may reduce CRC strength 
there...

Anyway, saing zlib not to add adler32 CRC is good idea and I think should 
be done.
