Yes, this is a "feature".  It's pretty well wired into GDB.  It might
be possible to make insert_breakpoints() and remove_breakpoints() do
some sort of caching-like thing, but I'm not sure that all target
memory reads know about substituting original code, so you might get
punished when you're doing disassembly or prologue analysis.
