Summary	0000262: Supporting break command with minimum overhead
Description	Currently Xdebug does not accept break command while the language engine is running. I guess that the main reason of it is performance. Checking in-comming command on every statement execution is too expensive. May be my guess is wrong. So, how about checking in-comming (break) command every 100 (or 255, whatever) statements execution. static unsigned char counter = 0; if (++counter == 0) { / check for incomming break/status command / ... } This way, performance down should not be so bad, and at least I can break the target execution from debugger client without restarting Apache ;-)
