Or extra 2 minutes in my case :-(

Note that the gdb-breakpoint-20090505.txt patch did not deactivate
breakpoint reset. It merely turned an O(N*N) operation into O(N)
operation, by resetting breakpoints once, after all solib symbols
have been loaded.

Because of that, your "maintenance set ..." suggestion doesn't
make sense to me: why would you ever want O(N*N) algorithm when an
O(N) one is available?
