It's been suggested to me that we should create a hacked gdb that 
records all commands et.al. to a file, and then offers to send them to 
us.  That way we know what is, rather than what might be.

If we knew for instance that only 10% of users set breakpoints outside 
of the main executible, then we'd also know that we were frustrating 90% 
of users by making them sit around waiting for needless symbol table 
reads :-(

On the other hand, if we knew that the first thing people did was:
	(gdb) break <tab>
we'd have an entirely different problem.
