materializing a MaCommitLogRecord

[Dave Woodward]

I'm wondering if it is possible to directly materialize the objects in a 
MaCommitLogRecord instance.

It seems that the commit log records are used exclusively for 
"advancing" the repository.  However I'm wondering if I can use the 
commit log as a sort of poor-man's audit log and if I'd be able to 
manually extract objects from specific commit log records.  Right now 
when I try to materialize a record in Pharo 1.0, I get an error because 
the serializer tries to call basicNew: on the MagmaLocalLocation class.

I'm not sure if this is even a good path to take, so fell free to tell 
me I'm crazy or that I shouldn't go there :)

I'm also wondering if the commits could be "rolled back" so as to be 
able to rewind the database back to a specific commit?  I see how one 
can restore up to a certain point in time, but I'm just wondering if 
there is any more specific way to "un-apply" the commit records.
