+
+ Since these numbers have actually made it out into other software

+ numbered signals.
+
+ This is based strongly on Unix/POSIX signals for several reasons:
+ (1) This set of signals represents a widely-accepted attempt to
+ represent events of this sort in a portable fashion, (2) we want a
+ signal to make it from wait to child_wait to the user intact, (3) many
+ remote protocols use a similar encoding. However, it is
+ recognized that this set of signals has limitations (such as not
+ distinguishing between various kinds of SIGSEGV, or not
+ distinguishing hitting a breakpoint from finishing a single step).
+ So in the future we may get around this either by adding additional
+ signals for breakpoint, single-step, etc., or by adding signal
+ codes; the latter seems more in the spirit of what BSD, System V,
