3e1d403bae LazDebuggerFp, FpDebug: Attach and Detach (Windows/Linux) 
Attach on Linux does not work for apps started with "run without debugging". (Maybe/Probably because the IDE does a separate waitpid on those, and interferes with the waitpid of the debugger?)

c946f67b86 FPDebugger: Prevent "internal events" (in debug loop) from changing the debugger state.
