FYI, testRecover.py tries to ensure that fsrecover isn't completely hosed -- but, AFAICT, it's almost impossible for a test in testRecover.py to fail(!).  I'm adding a new test there that doesn't deliberately damage the input .fs, and that new test is generated scads of error msgs too.  However, testRecover.py suppresses all the error output, so the test thinks it passed.  This will take some doing to untangle.

fsrecover.py is broken on current zope HEAD...         
... either that, or brand-new filestorages created by zope                 
really are corrupted.                                                           
                                                                                
To reproduce:                                                                   
- create a fresh Zope instance                                                  
- start zope                                                                    
- stop zope                                                                     
- run fsrecover.py on the brand new Data.fs                                     
                                                                                
Result is about 900 lines like this:   
                                           
0 . 1 . 2 . 3 . 4 . 5 . 6 . 7 . 8 error reading txn header: invalid transaction length, 0, at 1369028
