signal handling in 4.2: Is this still UNIX?

So they "broke" the signal handling in 4.2. Assuming that the new
implementation is correct (i.e., bug-free), I like it better. It
certainly more closely models interrupt handling. You wouldn't expect a
hardware interrupt to kill off your system call, so why should a
software interrupt? If you really want to quit out of whatever was
going on, then use longjmp.
