Process record and reverse debugging

[Anthony Green]

I've been using the process record feature for reverse debugging my 
linux kernel bring-up:  http://moxielogic.org/blog/?p=310

While I have found it useful, it would be nice if there was some way to 
coalesce the "undo" records for certain functions.   For instance, 
memset calls can generate a lot of records but they're usually not 
interesting from a debugging perspective.  I'm not sure the best way to 
handle this, but it seems like you could special-case some well known 
functions and treat them the same way system calls are handled.
