| 233 | This is based strongly on Unix/POSIX signals for several reasons: |
| 234 | (1) This set of signals represents a widely-accepted attempt to |

| 236 | signal to make it from wait to child_wait to the user intact, (3) many |
| 237 | remote protocols use a similar encoding. However, it is |
| 238 | recognized that this set of signals has limitations (such as not |
| 239 | distinguishing between various kinds of SIGSEGV, or not |
| 240 | distinguishing hitting a breakpoint from finishing a single step). |
| 241 | So in the future we may get around this either by adding additional |
| 242 | signals for breakpoint, single-step, etc., or by adding signal |
| 243 | codes; the latter seems more in the spirit of what BSD, System V, |
