If I understand you correctly, I think there's no problem.

You want to be able to reverse-continue to a point in the execution 
history that is earlier than when gdb attached -- right?

Should be ok -- gdb doesn't really 'know' anything special
about the point in "time" when it attached.

Sounds like a good idea.  Maybe a 'q' query?
"qReverse", maybe?
