New issue 89 by deepreds: writeback = True option for large memory machine
http://code.google.com/p/pygr/issues/detail?id=89

A few years ago, memory was expensive and most linux machines did not have  
large memory.
Thus, in order to reduce memory usage, all shelve files are saved  
as "writeback=False". The problem
is that it takes much greater time to generate shelve files rather than  
NLMSA.

If we have a large memory machine, we can greatly save time by just  
changing writeback=False into
writeback=True. Everything is done in memory and saved once when shelve  
closes.

I propose unified option for changing writeback status, from False  
(default) to True.
