enter/exit code. There's no real reason not to keep kernel breakpoints enabled when in userland (unless there are breakpoints installed for the team, of course). * Enabled kernel breakpoints by default (check your kernel_debug_config.h, if you have overridden it!), since they don't really add any overhead anymore. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30206 a95241bf-73f2-0310-859d-f6bbb57e9c96
