At one point we will need to come up with a better way to control these features.

I'm still evaluating whether to implement on the kernel side PT_SET_SIGPASS/PT_GET_SIGPASS. Some software like floating point can use it heavily.

Also there are programs which use SIGALRM or realtime signals very extensively, and those can get very much slowed down by a debugger. I think this would be a great addition, particularly as stopping a process is a much heavier operation on netbsd. I wish linux had that.
