Yes it is. :)  Actually it seems there might be a potentially useful
mechanism for fault injection in dprobes/kprobes.  I've thought so for a
long time but havn't had time to pursue it.  I think I did hear
something about a project recently that is aiming to build a fault
injection tool using kprobes though.  I .... was going to tell you to
google for it but you piqued my interest again.  It's at
fault-injection.sourceforge.net.  I don't know anything more about it
right now, or about how far along they are though.

Thanks,
