I always thought (speculated) that breakpoint removal was to simplify 
things like

    (gdb) x /i $pc

Where you don't want to see the INT instruction, but the original value.
GDB crash does sound like another reason.
Being curios, I'd like to ask what was the original reason for
this behavior? Does anyone know? I never saw it documented anywhere.
